What problem does this PR solve?
Issue Number: close #9529
Problem Summary:
we get the "suqash delete range" to estimate whether there are sufficient delete rows that we need to compact data in background thread.
tiflash/dbms/src/Storages/DeltaMerge/DeltaMergeStore_InternalBg.cpp
Lines 526 to 528 in ce0d411
In
ColumnFileSetSnapshot::getSquashDeleteRange
, it use the member variableis_common_handle
,rowkey_column_size
to generate the rowkey range.But actually those two variable are not set correctly.
is_common_handle
is always false inColumnFileSetSnapshot
tiflash/dbms/src/Storages/DeltaMerge/ColumnFile/ColumnFileSetSnapshot.cpp
Lines 21 to 30 in ce0d411
So when the table use common-handle,
shouldCompactDeltaWithStable
always returns false, and the segment background gc is not GC in timelyWhat is changed and how it works?
ColumnFileSetSnapshot::{is_common_handle, rowkey_column_size}
shouldCompactDeltaWithStable
