One of the interesting things about attending industry events, like AWS re:Invent, is identifying common trends that arise in conversations. Recent conversations point to a renewed interest in “enterprise ready replication” for NoSQL databases.
As business data continues to grow, there is an entirely new set of challenges that are presented related to availability, scalability, and fault-tolerance. While most NoSQL databases work at small scale, availability is often compromised as applications reach full production or peak capacity. Having the right replication functionality is key to ensuring that availability requirements are not compromised as your system grows.
“Replication” may mean different things based on context. In this case, we are referring to the movement of data in a database cluster — or across datacenters — for the purpose of redundancy or data locality. If your database experience began in an RDBMS context, then replication implies a specific contextual understanding of multi-master transactional deployment and, perhaps, shipping transaction logs between incremental backups in a hot/warm database configuration. In contrast, for those who began in the NoSQL era, the term may evoke images of replica-sets on a sharded infrastructure and the operational overhead associated therewith.
In a distributed NoSQL database, like Riak, the term replication is used to encompass two distinct concepts. First, intra-cluster replication for high availability and fault tolerance within the datacenter; and second, multi-datacenter replication for data locality and global availability. There is none of the complexity of log shipping or dealing with a sharded infrastructure.
Data replication is a core feature of Riak’s basic architecture. Riak was designed to operate as a clustered system containing multiple nodes (commodity servers or cloud instances). The replication implementation allows data to live on multiple machines at once, with a single write request, in case a node in the cluster goes down or is unavailable due to issues like network partitioning.
Intra-cluster replication is fundamental and automatic in Riak, so that your data is always available. All data stored in Riak is replicated to a number of nodes in the cluster according to a configurable parameter (
n_val) set in a buckets bucket type.
With the default
n_val setting of 3, there are always three copies of all data. These copies will be on three different partitions/vnodes. A detailed explanation and analysis of this replication capability is discussed in the Riak documentation – Understanding replication by example.
In the case of intra-cluster replication, or what we would refer to simply as “replication”, data distribution ensures redundant data such that high availability is maintained in a failure state.
In contrast to intra-cluster replication, multi-datacenter replication (a feature of Riak Enterprise) is a critical part of modern application infrastructures. Riak Enterprise offers multi-datacenter replication features so that data stored in Riak can be replicated to multiple sites (vs. multiple servers in the same site).
As we are all aware, understanding application latency (for an end user) begins with the realization data can’t travel faster than the speed of light. So, inherently, as source information moves further from it’s consumption latency is introduced. As such, there is a set amount of latency for a customer connecting to your application hosted in New York when they are accessing the application from San Francisco. This latency profile increases, and becomes more complex, as the geographic distribution of your customer base increases.
With multi-datacenter replication in Riak Enterprise, data can be replicated across locations and geographic areas providing for disaster recovery, data locality, compliance with regulatory requirements, the ability to “burst” peak loads into public cloud infrastructure, amongst others.
Riak’s multi-datacenter replication is masterless. One cluster acts as a primary, or source, cluster. The primary cluster handles replication requests from one or more secondary, or sink, clusters (generally located in datacenters in other regions or countries). If the datacenter with the primary cluster goes down, a secondary cluster can automatically take over as the primary cluster.
More architectural strategies for multi-datacenter implementations, are covered in the Basho whitepaper entitled Riak Enterprise: Multi-Datacenter Replication – A Technical Overview & Use Cases or in the Basho Documentation section Multi-Datacenter Replication: v3 Architecture.
Replication, inside a cluster, is a core design tenant of Riak. This is used to provide the availability and fault-tolerance characteristics — with a low operational overhead — that many unstructured data workloads demand.
Multi-datacenter replication, while related, is an entirely different approach and architecture to enable the geographic distribution of data to solve for redundancy, geo-data locality, etc.
Replication is an important scalability feature of any database deployment. Ensuring that your NoSQL database replicates data in a way that is scalable, operationally simple and achieves your business objectives is key to your success.
London, Sept. 9 2014 – the Spine – the electronic backbone of the UK’s National Health Service – has been successfully rebuilt to harness new technology, including the use of Basho Technologies’ distributed database, Riak Enterprise.
The Spine – a collection of national applications, services and directories – connects clinicians, patients and local service providers throughout England to essential national services, such as electronic prescriptions and patient health records.
Spine is used by more than 20,000 organizations that provide health care across England, including primary and secondary care sites, pharmacies, opticians and dentists. Riak, the open source distributed database, is key to providing the reliability and scalability for the platform to drive efficiency and improve patient care.
The NHS’ move to revamp the Spine, in a major project led by England’s Health and Social Care Information Centre (HSCIC), was driven by the need for a scalable, resilient and flexible system that would also result in cost-savings for the organization.
With these requirements in mind, the NHS selected Riak Enterprise, the commercial version of Basho’s distributed open source, highly available NoSQL database, to support the transition and implementation of the new Spine. Basho and the HSCIC collaborated throughout to ensure the technical knowledge of both organizations was reflected in enhancements to Riak and the wider project itself.
Riak has been tested thoroughly over the past year and will also allow the NHS to update the Spine seamlessly, removing interruptions which could adversely affect NHS employees and patients.
The transition was finalised over the weekend of 22nd August, 2014, with the infrastructure undergoing a 45-day period of intensive monitoring to ensure that it is performing as expected.
“The improvement of patient care is of the utmost importance in the healthcare industry. As data, such as patient records, prescriptions and all other medical information becomes digitized, it is vital that government health organizations can adapt and provide constant, reliable access to this information,” said Adam Wray, CEO at Basho Technologies.
Stuart McCaul, Managing Director, EMEA at Basho Technologies said, “The information stored on the Spine is potentially life-saving, and so users must be able to quickly access the data they require without delay or complication. Riak has previously been adopted by other healthcare services outside of the UK, such as The Danish Health and Medical Authority, and it provides the Spine with resiliency and predictable scalability while also saving the NHS both time and costs, contributing to the improvement of patient care in England.”

Business Intelligence makes it possible for organizations to make sense of the vast amount of customer, manufacturing and competitive information they have available in order to make smarter and better informed decisions. In turn, this enables organizations to become more responsive to customer needs, increase efficiencies in manufacturing processes, and respond to significant events quickly.
Historically the data that drives business intelligence has been stored in structured formats in a data warehouse, such as customer information on how much is spent. However, this approach misses out on the value of semi-unstructured and unstructured data, like the details from a customer call or a customer tweet.
With such information missing, a complete view of the customer or business can be limited. The consequence is that an inability to gain knowledge and measure customer information means businesses can fall behind, especially in a competitive market.
Business Intelligence needs NoSQL
Having access to all types of relevant customer information – structured, semi-structured and unstructured – is an essential requirement for business intelligence (BI) to help enterprises get ahead of the competition. Unlike structured, relational data warehouses, NoSQL databases make this possible with improved availability, scalability and fast response times. NoSQL databases are ideal for BI and data warehousing not only because of the diverse types of information it can deal with, but also because they are able to deliver data at the very time it is needed.
Enabling real-time analytics
NoSQL keeps up with transaction speeds as-it-happens, enabling real-time analytics. E-commerce transactions, for example, benefit from a NoSQL database because it can make a decision about what to do next when a buyer doesn’t complete a purchase. Instead of waiting 24 hours or longer for the data to move through a traditional data warehouse system, with a NoSQL system a feed goes straight from a transaction through a connecter to a NoSQL database. A sales analytics process can make a decision with the intelligence at that very minute, to consult the customer and understand the behavior in real-time, helping secure the purchase and preventing the loss of a customer transaction.
A recently announced Basho partner, Caserta Concepts, a technology consulting firm specializing in big data analytics, data warehousing and business intelligence, works with CIOs to deliver analytics solutions that support business goals. It uses Riak and Riak CS to accommodate unique client requirements across a broad range of data types – structured, semi-structured and unstructured – and provides continuous availability to keep critical line-of-business applications going around the clock. Caserta’s practice illustrates the viability for NoSQL in the database revolution to take on the volume, variety and velocity of data dynamics of today’s web-scale applications.
Intelligence for IoT transactions
With the vast amounts of information from Internet of Things (IoT) technologies, more business intelligence needs and use cases are at the cusp. Consider oil and gas organizations providing annual service contracts for boilers – analytics tells the business that anything beyond the second call out (or truck roll) wipes out the profit on the contract. In the connected world, NoSQL enables the next level of intelligence, which allows organizations to collect information so that, in the event of failure, they are able to determine which parts are needed in advance, eliminating the need for multiple visits. Gathering intelligence from this data also allows organizations to perform preemptive maintenance during the annual inspections to lower the frequency of unplanned, costly site visits.
With NoSQL, BI and data warehousing can become quicker and much more efficient. It allows organizations to react to events more quickly, increase customer attention, streamline the supply chain, predict customer behavior at the point it matters and predict future service calls. At the rise of big, unstructured data, NoSQL presents enormous opportunity for the future of business intelligence.
Basho is pleased to announce the release of Riak CS 1.5, which provides additional performance enhancements and simplifies administration and development with additional admin tools, enhanced S3 compatibility and a technical preview of an architecture to support clusters with very large amounts of storage. Highlights include:
- riak-cs-admin: Consolidates admin operations into a command line tool.
- riak-cs-stanchion: Changes the Stanchion IP and port.
- riak-cs-debug: Packages log, configuration and operating system command files along with Riak command results.
- syslog: Support for standardized syslog output for log aggregation using third-party tools.
S3 API Features
- multi-object delete: Reduces request overhead by supporting multiple deletes in a single request (up to 1,000 keys per request).
- cache control headers: Method for providing caching instructions in a request header.
- PUT object – copy: Creates a copy of an object that already exists in Riak CS.
A full list of S3 API compatibility can be found on the Basho docs site here.
Increased Scalability (Enterprise Feature)
Partly due to limitations with distributed Erlang, prior to 1.5 scalability, Riak CS was limited to several petabytes. CS 1.5 introduces a technical preview of an architecture that allows multiple Riak clusters to reside under a single CS namespace, thereby significantly increasing the amount of storage possible in a cluster. A production-ready version is planned for later this year, with multi-data center support to follow.
Garbage Collection Improvements
In Riak CS, deleted and updated objects are not removed immediately. Instead, a reference is written to a special bucket and later removed by the garbage collection process at regular intervals. CS 1.5 includes several garbage collection enhancements that will benefit customers with a high rate of object deletion or updates.
- concurrent garbage collection worker processes: Speed up the rate of garbage collection with the addition of multiple workers.
- flexible enforcement of leeway interval: In previous versions, updated and deleted objects are reaped only after they reach a predefined time-based leeway interval, which was set when an object was marked for deletion. In CS 1.5 the leeway interval is managed by the garbage collection daemon and can be changed to remove objects sooner, for example, in emergency situations where maximum storage capacity is reached.
Other Notable Enhancements
- faster bucket listings: Optimizations in the OTP xmerl library enables faster bucket listings, in particular for large buckets.
- setting ACLs upon PUT object: Ability to set ACLs via header at PUT object creation is now fully functional.
Riak CS 1.5 is available at: http://docs.basho.com/riakcs/latest/riakcs-downloads/. A full list of changes is available in the release notes. Watch the blog for a detailed discussion of the multi-cluster work.
Distributed cloud storage software adds additional Amazon S3 compatibility, performance improvements, simplified admin and increased scalability
CAMBRIDGE, Mass. – August 5, 2014 – Basho, the creator and developer of Riak, the industry leading distributed NoSQL database, today introduced Riak CS 1.5 and Riak CS 1.5 Enterprise, Basho’s distributed object storage software.

Today, we announced our newly expanded product portfolio. We have added many new offerings for both Riak and Riak CS to better meet the needs of our growing user base. You can check out prices and what’s been added here.
An Inside Look
In 2009, Basho first open sourced Riak. That decision has driven our culture, our development process, our business model, and – in large part – our current success. The Basho team strongly believes that open source drives adoption (a concept discussed at length in Stephen O’Grady’s book, The New Kingmakers). In addition to being a favorite of start-ups, open source continues to attract more and more IT organizations, enterprise architects, and CIOs.
Basho support for Riak and Riak CS open source users is at the heart of this expanded product portfolio. Since launching Riak 1.0 just over two years ago, providing guaranteed support for non commercial-software users has been a topic of much discussion within Basho. As a distributed database, Riak is built for mission-critical applications where any downtime is not tolerable, revenue is often on the line, and a bulletproof, low-latency customer experience is absolutely required.
Our Enterprise customers love our support. Fortune 500 customers that put Riak into production never leave Riak. Our front-line Client Services Engineers are all full-stack engineers who resolve issues directly. In 2013, Basho’s average time to first respond to an Urgent ticket was 11 minutes. The team also handled over 2,000 customer requests that ranged from Riak configuration questions and performance tuning, to application design and full-stack inquiries. Some recent examples of customer praise:
Scott Densmore with CenturyLink
Loving the support from @basho! These guys are awesome!
— Scott Densmore (@scottdensmore) December 27, 2013
Brian Akins at Turner Broadcasting
Huge shout out to @basho for saving our bacon
— Brian Akins (@bakins) October 17, 2013
In addition to our Enterprise customers, we also have a fast-growing community of users that are in different stages of their software development lifecycle. Our Enterprise level of support (24×7) may not always be necessary. Many early-stage users simply do not yet require the advanced features of Riak Enterprise and Riak CS Enterprise, such as Multi-Datacenter Replication.
As Basho has transitioned from start-up to growth stage, we’ve continued to evaluate how we can continue the ultra-high support experience our Enterprise customers have come to rely on, while expanding support to other users. This expanded product portfolio allows us to do both.
The Finer Details of the New Portfolio
For both Riak and Riak CS, we now offer four levels of service: Starter, Basic, Enterprise, and Enterprise Plus. All of these options combine the built-in benefits of open source Riak and Riak CS with Basho engineering support, providing access to our global team of Client Services Engineers for assistance.
All tiers offer online ticket tracking for issues and Enterprise and Enterprise Plus also offer emergency patches. SLAs are available for guaranteed ticket response by a Basho engineer:
- 12-hour guarantee for Starter
- 1-hour guarantee for Basic
- 30-minute guarantee for Enterprise and Enterprise Plus
- Enterprise and Enterprise Plus also offer a continuous support availability option during customer special events
Finally, as with Riak Enterprise and Riak CS Enterprise in the past, both Enterprise and Enterprise Plus include Multi-Datacenter Replication (which also enables cluster-to-cluster replication for secondary workloads), reduced replicas at secondary sites for more efficient storage, and SNMP and JMX Support. Enterprise Plus adds a Basho baseline and annual health check, which provides added Basho assurance and ensures long-term platform stability and performance. All Enterprise offerings include a commercial license – providing more flexible permitted usage.

Update on Riak 2.0
Basho anticipates the general availability of Riak 2.0 within the next 75 days. All Basho customers will have immediate access to customer support and Riak 2.0 software code at that time, subject to the support terms of their product tier. For more information on Riak 2.0, visit our blog: basho.com/introducing-riak-2-0/.
October 29, 2013
Throughout RICON West, we will be discussing many of the Riak 2.0 features (both in track sessions or during lightning talks), so keep your eyes on the live stream over the next two days. Videos of all sessions will also be made available after the conference.
Here is a look at some of the major enhancements available in Riak 2.0:
- Riak Data Types. Building on the eventually consistent counters introduced in Riak 1.4, Riak 2.0 adds sets and maps as new distributed data types. These Riak Data Types simplify application development without sacrificing Riak’s availability and partition tolerance characteristics.
- Strong Consistency. Developers have the flexibility to choose whether buckets should be eventually consistent (the default Riak configuration today that provides high availability) or strongly consistent, based on data requirements.
- Full-Text Search Integration with Apache Solr. Riak Search is completely redesigned in Riak 2.0, leveraging the Apache Solr engine. Riak Search in 2.0 supports the Solr client query APIs, enabling integration with a wide range of existing software and commercial solutions.
- Security. Riak 2.0 adds the ability to administer access rights and utilize plug-in authentication models. Authentication and Authorization is provided via client APIs.
- Simplified Configuration Management. Riak 2.0 continues to improve Riak’s operational simplicity by changing how, and where, configuration information is stored in an easy-to-parse and transparent format.
- Reduced Replicas for Multiple Data Centers. Riak Enterprise 2.0 can optionally store fewer copies of replicated data across multiple data centers to better maintain a balance between storage overhead and availability.
Ready to get started? Download the Technical Preview.
Please note that this is only a Technical Preview of Riak 2.0. This means that it has been tested extensively, as we do with all of our release candidates, but there is still work to be completed to ensure it’s production hardened. Between now and the final release, we will be continuing manual and automated testing, creating detailed use cases, gathering performance statistics, and updating the documentation for both usage and deployment.
Riak 2.0 Technical Preview: Deep Dive
Riak Data Types
In distributed systems, we are forced to trade consistency for availability (see: CAP Theorem) and this can complicate some aspects of application design. In Riak 2.0, we have integrated cutting-edge research on data types known as called CRDTs (Conflict-Free Replicated Data Types) pioneered by INRIA to create Riak Data Types. By adding counters, sets, maps, registers, and flags, these Riak Data Types enable developers to spend less time thinking about the complexities of vector clocks and sibling resolution and, instead, focusing on using familiar, distributed data types to support their applications’ data access patterns.
A more detailed overview of Riak Data Types is available that examines implementation considerations and the basics of usage.
In all prior versions, Riak was classified as an eventually consistent system. With the 2.0 release, Riak now lets developers choose when operations should be strongly or eventually consistent. This gives developers a choice between these semantics for different types of data. At the same time, operators can continue to enjoy the operational simplicity of Riak. Consistency preferences are defined on a per bucket type basis, in the same cluster.
A RICON West 2012 talk entitled, Bringing Consistency to Riak, shares much of the initial thinking behind this effort. In addition, the pull request that adds consistency to
riak_kv provides detailed information about related repositories and the implementation approach.
Redesigned Full-Text Search
Riak is a key/value store and the values are simply stored on disk as binary. With previous versions of Riak Search, Riak developers have long been able to index the content of these stored values. In Riak 2.0, Riak Search (code-named Yokozuna) has been completely redesigned and now uses the Apache Solr full-text document indexing engine directly. Together, Riak and Solr provide a reliable full-text context indexing solution that is highly available and built for scale. In addition, Riak Search 2.0 also fully supports the Solr client query APIs, which enables integration with existing software solutions (either homegrown or commercial).
The Basho engineers responsible for Yokozuna have created a resources page that includes recorded talks, Solr documentation links, and books on the topic.
Basho designed Riak with critical data in mind. Whether it’s data that affects revenue, user experience, or even a patient’s health (as is the case with the NHS), Riak ensures that this critical data is always available. However, often this critical data is also sensitive data. Riak 2.0 adds security to this data through the ability to administer access rights and plug-in various secure authentication models commonly used today.
The initial RFC that describes the security effort, including related Pull Requests, is available at github.com/basho/riak/issues/355.
Simplified Configuration Management
At Basho, we pride ourselves on providing operationally friendly software that functions smoothly when dealing with the challenges of a distributed system. In the past, configuration of Riak occurred in two files:
vm.args. Riak 2.0 changes how and where configuration information is stored. It no longer uses Erlang-specific syntax but, rather, provides a layout more suited for all operators and automated deployment tools. This layout is easy to parse and transparent for Riak administrators.
More information on the vision and specific implementation considerations are contained in the repository at github.com/basho/cuttlefish.
In versions of Riak prior to 2.0, keys were made up of two parts: the bucket they belong to and a unique identifier within that bucket. Buckets act as a namespace and allow for similar keys to be grouped. In addition, they provide a means of configuring how previous versions of Riak treated that data.
In Riak 2.0, several new features (security and strong consistency in particular) need to interact with groups of buckets. To this end, Riak 2.0 includes the concept of a Bucket Type. In addition to allowing new features without special prefixes in Bucket names, Riak developers and operators are able to define a group of buckets that share the same properties and only store information about each Bucket Type, rather than individual buckets.
More information about Bucket Types can be found in the Github Issue at github.com/basho/riak/issues/362. This issue describes the planned functionality, discussions about implementation, and includes related pull requests.
Change in Defaults for Sibling Resolution
Riak has always supported both application-side and timestamp and vector clock-based Last Write Wins server-side resolution. Prior to Riak 2.0, vector clock-based Last Write Wins has been the default. Moving forward, new clusters will hand off siblings to applications by default. This is the safest way to work with Riak, but requires developers to be aware of sibling resolution.
More Efficient Use of Physical Memory
Riak nodes are designed to manage the changing demands of a cluster as it experiences network, hardware, and other failures. To do this, Riak balances each node’s resources accordingly. Riak 2.0 has vastly improved LevelDB’s use of available physical memory (RAM) by allowing local databases to dynamically change their cache sizes as the cluster fluctuates under load.
In the past, it was necessary to specify RAM allocation for different LevelDB caches independently. This is no longer the case. In Riak 2.0, LevelDB databases that manage key/value or active anti-entropy data share a single pool of memory, and administrators are free to allocate as much of the available RAM to LevelDB as they feel is appropriate in their deployment. Detailed implementation documentation can be found in the basho/leveldb wiki.
Riak Ruby Vagrant Project
If you are interested in testing Riak 2.0, in a contained environment with the Riak Ruby Client, Basho engineer Bryce Kerley has put together the Riak-Ruby-Vagrant repository. In addition, this environment can be easily adapted to usage with other clients for testing the new features of Riak 2.0.
