Version 5.1.1¶

Released on 2022-11-09.

Note

If you are upgrading a cluster, you must be running CrateDB 4.0.2 or higher before you upgrade to 5.1.1.

We recommend that you upgrade to the latest 5.0 release before moving to 5.1.1.

A rolling upgrade from 5.0.x to 5.1.1 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 that prevented _id IN (SELECT ...) from matching records.
Fixed an issue that could lead to a class_cast_exception error when using ORDER BY on a column of type TEXT or VARCHAR.
Changed the logic to resolve functions. Previously it would first look for built-ins for all schemas within the search path before looking up user defined functions. Now it will search for built-in and UDF per schema to prioritize UDFs earlier in the search path over built-ins later in the search path.
Fixed an issue that could lead to a encoded value getting returned for bit columns that are part of an object column.
Fixed an issue that caused incorrect results to be returned when using array(subquery) when the subquery is using ORDER BY on a different column than the one returned, i.e.:
```
SELECT array(SELECT country FROM sys.summits ORDER BY height DESC LIMIT 3)
```

Fixed an issue that prevented defining a bit column with the same name as the parent object within a table. i.e.:

CREATE TABLE tbl (x OBJECT AS (x bit(1)))
                  ^            ^

Fixed an issue that could lead to out of memory errors if using the percentile aggregation.
Fixed an issue that could lead to serialization errors when using the bit type in objects.
Fixed an issue that could lead to IllegalIndexShardStateException errors when running a SELECT count(*) FROM tbl on partitioned tables.

Fixed an issue which caused PRIMARY KEY columns to be required on insert even if they are generated and their source columns are default not-null, i.e.:

CREATE TABLE test (
  id INT NOT NULL PRIMARY KEY,
  created TIMESTAMP WITH TIME ZONE DEFAULT current_timestamp NOT NULL,
  month TIMESTAMP GENERATED ALWAYS AS date_trunc('month', created) PRIMARY KEY
);

INSERT INTO test(id) VALUES(1);

Fixed an issue that could cause COPY FROM, INSERT INTO, UPDATE and DELETE operations to get stuck if under memory pressure.

Fixed an issue that didn’t allow queries with a greater than 0 OFFSET but without LIMIT to be executed successfully, i.e.:

SELECT * FROM test OFFSET 10
SELECT * FROM test LIMIT null OFFSET 10
SELECT * FROM test LIMIT ALL OFFSET 10

Fixed an issue that caused col IS NULL to match empty objects.
Fixed an issue that caused ARRAY_COL = [] to throw an exception on OBJECT, GEO_SHAPE, IP or BIT array element types.
Fixed an issue that caused queries reading values of type BIT to return a wrong result if the query contains a WHERE clause pk_col = ? condition.
Fixed an issue that prevented NOT NULL constraints on GEO_SHAPE columns from showing up in SHOW CREATE TABLE statements.
