Couchbase 4.5 Developer Preview

As we head towards 4.5 GA, this is a significant milestone packed with many exciting features for more efficient querying, advanced data access, powerful indexing, and more comprehensive administration.

For developers, this is going to be a big preview release as it brings some exciting features including:

  • Query Workbench – a built-in query editor for writing and executing queries as well as exploring the data model with automatically inferred schemas
  • Full-text Search – support for term, fuzzy, phrase, match, and prefix queries has been added – faceting, scoring, and highlighting, too.
    • Blog: Full-text Search in Couchbase 4.5 Developer Preview by @ldoguin and @willgardella
    • Blog: Preview of Full-text Search in Couchbase using the Java SDK by @simonbasle
  • Sub-document API – enables clients to add, remove, and modify individual fields (or read them), including objects and arrays, without reading and writing the entire document
    • Blog: Sub-documents: find and change only what you need by @matthewrevell
  • Array Indexing – index specific fields of elements within nested arrays to improve query performance
  • Extended N1QL joins – support a new query optimization for filtering the right side first, with an index, resulting in added flexibility and improved query performance
  • Query Profiling and Monitoring – monitor active queries and connections as well as profile queries to identify and diagnose performance issues
  • Many more

We’ve also introduced Debian 8 builds and this adds to the existing wide list of platforms we already run on.
