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.

[RFC] Replacing merge tree new engine (#41005) * Add new engine to ReplacingMergeTree corresponding to the ReplacingCollapsingMergeTree * Add new test for the new ReplacingMergeTree engine * Limit sign value to -1/1 * Add new engine to ReplacingMergeTree corresponding to the ReplacingCollapsingMergeTree * Add new test for the new ReplacingMergeTree engine * Limit sign value to -1/1 * Replace sign column(Int8) by is_deleted(UInt8) * Add new engine to ReplacingMergeTree corresponding to the ReplacingCollapsingMergeTree * Add new test for the new ReplacingMergeTree engine * Limit sign value to -1/1 * Replace sign column(Int8) by is_deleted(UInt8) * Add new engine to ReplacingMergeTree corresponding to the ReplacingCollapsingMergeTree * Add new test for the new ReplacingMergeTree engine * Limit sign value to -1/1 * Replace sign column(Int8) by is_deleted(UInt8) * Add keyword 'CLEANUP' when OPTIMIZE * Cleanup uniquely when it's a replacingMergeTree * Propagate CLEANUP information and change from 'with_cleanup' to 'cleanup' * Cleanup data flagged as 'is_deleted' * Fix merge when optimize and add a test * Fix OPTIMIZE and INSERT + add tests * New fix for cleanup at the merge * Cleanup debug logs * Add the SETTINGS option 'clean_deleted_rows' that can be 'never' or 'always' * Fix regression bug; Now REplicatedMergeTree can be called as before without 'is_deleted' * Add Replicated tests * Disable tag 'long' for our test and cleanup some white spaces * Update tests * Fix tests and remove additional useless whitespace * Fix replica test * Style clean && add condition check for is_deleted values * clean_deleted_rows settings is nom an enum * Add valid default value to the clean_deleted_rows settings * Update cleanup checkers to use the enum and fix typos in the test * Fix submodule contrib/AMQP-CPP pointer * Add missing messages in test reference and remove a print with non derterministic order * fix replica test reference * Fix edge case * Fix a typo for the spell checker * Fix reference * Fix a condition to raise an error if is_deleted differ from 0/1 and cleanup * Change tests file name and update number * This should fix the ReplacingMergeTree parameter set * Fix replicated parameters * Disable allow_deprecated_syntax_for_merge_tree for our new column * Fix a test * Remove non deterministic order print in the test * Test on replicas * Remove a condition, when checking optional parameters, that should not be sueful since we disabled the deprected_syntaxe * Revert "Remove a condition, when checking optional parameters, that should not be useful since we disabled the deprected_syntaxe" This reverts commit b65d64c05e482945ac20fcfcf0311e1b028ea137. * Fix replica management and limit the number of argument to two maximum, due to the possiblity of deprecated table create/attach failing otherwise * Test a fix for replicated log information error * Try to add sync to have consistent results * Change path of replicas that should cause one issue and add few prints in case it's not that * Get cleanup info on replicas only if information found * Fix style issues * Try to avoid replication error 'cannot select parts...' and and replica read/write field order * Cleanup according to PR reviews and add tests on error raised. * Update src/Storages/MergeTree/registerStorageMergeTree.cpp Co-authored-by: Alexander Tokmakov <tavplubix@gmail.com> * Select ... FINAL don't show rows with is_deleted = true * Update and fix SELECT ...
