70ea507dae OPTIMIZE DEDUPLICATE BY columns 
Extended OPTIMIZE ... DEDUPLICATE syntax to allow explicit (or implicit with asterisk/column transformers) list of columns to check for duplicates on.

Following syntax variants are now supported:

OPTIMIZE TABLE table DEDUPLICATE; -- the old one
OPTIMIZE TABLE table DEDUPLICATE BY *;
OPTIMIZE TABLE table DEDUPLICATE BY * EXCEPT colX;
OPTIMIZE TABLE table DEDUPLICATE BY * EXCEPT (colX, colY);
OPTIMIZE TABLE table DEDUPLICATE BY col1,col2,col3;
OPTIMIZE TABLE table DEDUPLICATE BY COLUMNS('column-matched-by-regex');
OPTIMIZE TABLE table DEDUPLICATE BY COLUMNS('column-matched-by-regex') EXCEPT colX;
OPTIMIZE TABLE table DEDUPLICATE BY COLUMNS('column-matched-by-regex') EXCEPT (colX, colY);

Note that * behaves just like in SELECT: MATERIALIZED, and ALIAS columns are not used for expansion.
Also, it is an error to specify empty list of columns, or write an expression that results in an empty list of columns, or deduplicate by an ALIAS column.
Column transformers other than EXCEPT are not supported.

Merge pull request #14060 from azat/parallel_distributed_insert_select-2 
Extend parallel_distributed_insert_select to run INSERT into local table
 2020-08-26 20:37:36 +03:00

50a312534c Extend parallel_distributed_insert_select to run INSERT into local table 
Before this patch there was:

- parallel_distributed_insert_select=1, that executes:

    INSERT INTO dist_out SELECT ... FROM underlying_dist_in

After this patch there will be:

- parallel_distributed_insert_select=2, that executes:

    INSERT INTO underlying_dist_out SELECT ... FROM underlying_dist_in

And cover the behaviour w/o integration test, by using the following
techincs:
- SYSTEM STOP DISTRIBUTED SENDS
- prefer_localhost_replica=0
