ClickHouse release v21.4.5.46-stable FIXME as compared to v21.4.4.30-stable
Improvement
- Backported in #23273: Disable settings
use_hedged_requests
andasync_socket_for_remote
because there is an evidence that it may cause issues. #23261 (Alexey Milovidov).
Bug Fix
- Backported in #23234: Server might fail to start if
data_type_default_nullable
setting is enabled in default profile, it's fixed. Fixes #22573. #23185 (Alexander Tokmakov). - Backported in #23407: QueryAliasVisitor to prefer alias for ASTWithAlias if subquery was optimized to constant. Fixes #22924. Fixes #10401. #23191 (Maksim Kita).
- Backported in #23382: Fixed
Not found column
error when selecting fromMaterializeMySQL
with condition on key column. Fixes #22432. #23200 (Alexander Tokmakov). - Backported in #23385: Fixed the behavior when disabling
input_format_with_names_use_header
setting discards all the input with CSVWithNames format. This fixes #22406. #23202 (Nikita Mikhaylov). - Backported in #23287: Fixed simple key dictionary from DDL creation if primary key is not first attribute. Fixes #23236. #23262 (Maksim Kita).
- Backported in #23451: Fixed very rare (distributed) race condition between creation and removal of ReplicatedMergeTree tables. It might cause exceptions like
node doesn't exist
on attempt to create replicated table. Fixes #21419. #23294 (Alexander Tokmakov). - Backported in #23426: Fix possible crash in case if
unknown packet
was received form remote query (withasync_socket_for_remote
enabled). Maybe fixes #21167. #23309 (Nikolai Kochetov). - Backported in #23467:
ORDER BY
withCOLLATE
was not working correctly if the column is in primary key (or is a monotonic function of it) and the settingoptimize_read_in_order
is not turned off. This closes #22379. Workaround for older versions: turn the settingoptimize_read_in_order
off. #23375 (Alexey Milovidov). - Backported in #23509: Remove support for
argMin
andargMax
for singleTuple
argument. The code was not memory-safe. The feature was added by mistake and it is confusing for people. These functions can be reintroduced under different names later. This fixes #22384 and reverts #17359. #23393 (Alexey Milovidov). - Backported in #23478: Kafka storage may support
arrow
andarrowstream
format messages. #23415 (Chao Ma). - Backported in #23498: - Bug fix for
deltaSum
aggregate function in counter reset case ... #23437 (Russ Frank). - Backported in #23492: Fix bug that does not allow cast from empty array literal, to array with dimensions greater than 1. Closes #14476. #23456 (Maksim Kita).
- Backported in #23534: When modify column's default value without datatype, and this column is used as ReplacingMergeTree's parameter like column
b
in the below example, then the server will core dump:CREATE TABLE alter_test (a Int32, b DateTime) ENGINE = ReplacingMergeTree(b) ORDER BY a; ALTER TABLE alter_test MODIFY COLUMN `b` DEFAULT now();
