Changelog

Breaking Changes

  • Removed multicast discovery.
  • The ordinal column at the information_schema.columns will return NULL now for all sub-columns (all non top-level columns) as the order of object columns is not guarateed.
  • The TableFunctionImplementation interface was streamlined with other function implementation semantics. This requires function implementation plugins to be adapted to the new interface.
  • Removed deprecated setting indices.fielddata.breaker that have been used as an alias for indices.breaker.fielddata.

Changes

  • Serve admin UI from /. Previously used URIs will direct to /.
  • Added the subscript function support for object literals.
  • Added cluster checks that warn if some tables need to be recreated or upgraded for compatibility with future versions of CrateDB.
  • Added functionality to monitor query runtime statistics via JMX. This feature can only be used with an enterprise license.
  • Added a new parameter upgrade_segments to the OPTIMIZE statement which enables the upgrade of tables and tables partitions to the current version of the storage engine.
  • Added new column min_lucene_version to sys.shards table, which shows the oldest lucene segment version used in the shard.
  • Remove restriction to run OPTIMIZE on blob tables.
  • UDC: add the enterprise field to the UDC ping. The field identifies whether a user uses the enterprise version.
  • Added the license.enterprise setting to the cluster settings.
  • It is now supported to order and group by predicate functions in general with the exception of the match predicate.
  • Selecting os['timestamp'] from ``sys.nodes returns the actual timestamp of each node clock at the time of collecting the metric instead of the timestamp on the handler node.
  • Added scalar function geohash that returns a GeoHash representation of a geo_point
  • Added support for casting JSON strings to object columns.
  • The array comparison no longer requires extra parentheses for subselects. Now it’s possible to use `` = ANY (SELECT ...)`` instead of `` = ANY ((SELECT ...))``.
  • Allow semi-colon (;) in the end of simple SQL statements.
  • Enhanced performance optimisation of full joins by rewriting them to left, right or inner joins when conditions in WHERE exclude null values.
  • Added support for filtering and ordering on ignored object columns.
  • Added support for the double colon (::) cast operator.
  • Upgraded the parser from ANTLR3 to ANTLR4.
  • Added monitoring plugin for the Enterprise edition in the admin UI.
  • Added Lazy loading of the stylesheet and plugins depending on the Enterprise settings.
  • Added buttons to collapse and expand all schemas in the tables view.
  • The console now expands vertically to show the whole query if its size is larger than the standard size of the console.
  • SQL console keywords are now CrateDB specific.
  • Improved formatted results of the geo_area data type to include an external link to a visualisation of that geo_area.
  • Keywords in the SQL console are capitalised.
  • Added node number to the status bar.
  • Relocated the help resources section to be underneath the tweet import tutorial.
  • Improved console results table, including data type based colorization, alternating row colorization, structured object/array formatting, human-readable timestamps, Google Maps link on geo-point results & lazy loading on result sets larger than 100 rows.
