Closes: ClickHouse/ClickHouse#106845
What changed
The example demonstrating
parallel_view_processing=1was usingINSERT INTO source VALUES ('test'), which no longer honors thissetting since v25.5 (after PR #77309).
Updated the example to use
INSERT INTO source SELECT 'test'whichcorrectly demonstrates parallel view processing.
Also added a note clarifying that
parallel_view_processingonlyapplies to
INSERT ... SELECTqueries since v25.5.Changelog category
Note
Low Risk
Documentation-only change with no runtime or API impact.
Overview
Updates the Parallel vs sequential processing section so the
parallel_view_processing=1demo matches ClickHouse v25.5+ behavior.Adds a note that
parallel_view_processingapplies only toINSERT ... SELECT, notINSERT ... VALUES. The parallel example is changed fromINSERT INTO source VALUES ('test')toINSERT INTO source SELECT 'test', so readers can still see parallel MV execution and faster insert timing.Reviewed by Cursor Bugbot for commit 706f6ce.
