Version 2.1.8

Released on 2017/10/12.

Note

If you are upgrading a cluster, you must be running CrateDB version_1.1.3 or higher before you upgrade to 2.1.8.

If you want to perform a rolling upgrade, your current CrateDB version number must be version_2.1.0. If you want to upgrade from a version prior to this, the upgrade will introduce all of the breaking changes listed for version_2.1.0, and will require a full restart upgrade.

Consult the upgrade notes for Version 2.1.0 <version_2.1.0_upgrade_notes> when upgrading.

Warning

Before upgrading, you should back up your data.

Fixes

  • Fixed an issue that caused INSERT statements using a subquery <gloss-subquery> on the sys.shards system table to fail.
  • Fixed an issue that caused wrong results for JOIN queries on three or more tables when ORDER BY clause contains columns from more than one table.
  • Fixed a bug that caused incorrect results to be returned for JOIN queries when the table stats indicated that the left table of a join is smaller than the right.
  • Fixed passing arguments that contain spaces in the crate shell script.
  • Fixed an issue that caused a table that is not part of the doc schema to be unavailable/hidden if it gets closed using ALTER TABLE.
  • Fixed an issue where the query circuit breaker would be tripped after running several queries due to incorrect memory tracking. Subsequent operations would have failed due to the lack of circuit breaker cleanup.
