Couchbase is excited to announce the availability of Couchbase Analytics Developer Preview 3 (DP3).

Major Features:

  • Rich query language: Couchbase Analytics supports SQL++, a next-generation declarative query language that has much in common with SQL. However, SQL++ includes extensions appropriate for the nested, schema-optional or even schema-less world of modern NoSQL systems.
  • Common data model: Rather than requiring you to reform your data into a relational model for Analytics, Couchbase Analytics natively supports the same rich, flexible-schema document data model used in Couchbase Server.
  • Workload isolation: Queries in Couchbase Analytics run on dedicated nodes that process your complex resource intensive queries, thereby avoiding impact to the query latencies and throughput of your operational workloads.
  • High data freshness: Couchbase Analytics uses DCP, the same fast memory-to-memory protocol that Couchbase Server nodes use to synchronize data among themselves, so Analytics queries run on data that is synchronized in near real-time without the overheads of data migration or transformation.

Highlights in Developer Preview 3

The focus of Developer Preview 3 is unified administration: Analytics now lives in the overall Couchbase architecture as “just another service” in its world of managed Multi-Dimensional Services, and the Couchbase Console reflects that. Functionally, DP3 also includes support for secondary indexes. To summarize briefly, DP3 includes:

  • Integrated cluster management: System management for Analytics is now part of the server’s framework, including support for cluster resizing as well as initial support for rebalancing.
  • Integrated user experience: The Couchbase Console includes an Analytics Workbench that provides the same essential look and feel as the familiar Query Workbench for N1QL.
  • Secondary indexes: For running large Analytical queries, the data-parallel algorithms employed by Analytics provide high performance. To accelerate smaller- to medium-sized queries, Analytics now offers you the opportunity to create secondary indexes that it can exploit (in parallel, of course).
  • Multiple data source options: DP3 gives you the option to shadow data either from buckets in the Couchbase cluster in which the Analytics service resides or from buckets residing in a different (remote) Couchbase cluster.

With Octoberfest in full swing, one of the clear use cases for DP3 is an all-important activity: Beer Analytics :). The screen shot below will give you a preview of the new/integrated nature of DP3 by showing Analytics when it has just been readied to work on this use case:

The next screen shot shows how work in progress on this use case might look with the new Query Workbench. Here a Beer Analyst is using SQL++ to explore important beer characteristics by city, perhaps in order to plan their next weekend getaway:

There you have it. Please go ahead and give DP3 a try by downloading the binary and starting with its tutorial – which, coincidentally, is based on – you guessed it – Beer Analytics!
