Version 5.3.4

Released on 2023-07-11.

Note

If you are upgrading a cluster, you must be running CrateDB 4.0.2 or higher before you upgrade to 5.3.4.

We recommend that you upgrade to the latest 5.2 release before moving to 5.3.4.

A rolling upgrade from 5.2.x to 5.3.4 is supported. Before upgrading, you should back up your data.

Warning

Tables that were created before CrateDB 4.x will not function with 5.x and must be recreated before moving to 5.x.x.

You can recreate tables using COPY TO and COPY FROM or by inserting the data into a new table.

Fixes

• Fixed an issue introduced with CrateDB 5.3.0 resulting in failing writes, broken replica shards, or even un-recoverable tables on tables using a column definition with a IP data type and an explicit INDEX OFF. Any table that was created with INDEX OFF on a IP column and already written to with CrateDB version >= 5.3.0 should be recreated using e.g. INSERT INTO new_table SELECT * FROM old_table (followed by swap table ALTER CLUSTER SWAP TABLE new_table TO old_table) or restored from a backup.

• Improved error message to be user-friendly, for definition of CHECK at column level for object sub-columns, instead of a ConversionException.

• Added validation to prevent creation of invalid nested array columns via INSERT INTO and dynamic column policy.

• Fixed parsing of ARRAY literals in PostgreSQL simple query mode.

• Fixed value of sys.jobs_log.stmt for various statements when issued via the PostgreSQL simple query mode by using the original query string instead of the statements string representation.

• Fixed an issue that caused UPDATE and DELETE on tables with PRIMARY KEYs from ignoring non primary key symbols in WHERE clauses if the WHERE clauses contain PRIMARY KEYS, e.g.

  UPDATE test SET x = 10 WHERE pk_col = 1 AND x = 2; -- executed update with 'pk_col = 1' only, ignoring 'x = 2'
  

• Fixed an issue that could cause errors for queries with aggregations, UNION and LIMIT, e.g.

  SELECT a, avg(c), b FROM t1 GROUP BY 1, 3
  UNION
  SELECT x, avg(z), y FROM t2 GROUP BY 1, 3
  UNION
  SELECT i, avg(k), j FROM t3 GROUP BY 1, 3
  LIMIT 10
  

• Fixed an issue which prevented INSERT INTO ... SELECT ... from inserting any records if the target table had a partitioned column of a non-string type, used in any expressions of GENERATED or CHECK definitions.

• Fixed an issue which caused INSERT INTO ... SELECT ... statements to skip NULL checks of CLUSTERED BY column values.

• Fixed an issue that resulted in enabled indexing for columns defined as the BIT data type even when explicitly turning it of using INDEX OFF.

• Fixed an issue resulting in an exception when writing data into a column of type Boolean with disabled indexing using INDEX OFF.

• Fixed an issue that caused an exception to be thrown when inserting a non-array value into a column that is dynamically created by inserting an empty array, ultimately modifying the type of the column and then selecting this column by the row’s primary key, for example:

  CREATE TABLE t (id int primary key, o OBJECT(dynamic));
  INSERT INTO t VALUES (1, {x=[]});
  INSERT INTO t VALUES (2, {x={}});  /* this is the culprit statement, inserting an object onto an array typed column */
  
  SELECT * FROM t WHERE id=1;
  SQLParseException[Cannot cast object element `x` with value `[]` to type `object`]
  

  after the fix:

  SELECT * FROM t WHERE id=1;
  +----+-------------+
  | id | o           |
  +----+-------------+
  |  1 | {"x": null} |
  +----+-------------+
