Issue Number: close #9946
Problem Summary:
Some pages for local index in the ColumnFileTiny is not removed when doing MinorCompaction
tiflash/dbms/src/Storages/DeltaMerge/Delta/MinorCompaction.cpp
Lines 53 to 54 in 6fec03d
In
MinorCompaction::preparewe usewbs.removed_log.delPage(t_file->getDataPageId());to remove the ColumnFileTiny. But this will not remove the related LocalIndex page_id with the ColumnFileTiny. We must uset_file->removeData(wbs);to remove the ColumnFileTiny along with its LocalIndex page_ids.BTW,
SegmentSplit,SegmentMergeandSegmentDeltaMerge(MajorCompaction) callsDeltaValueSpace::recordRemoveColumnFilesPagesand can correctly remove the LocalIndex page_ids.What is changed and how it works?
