Rationale for this change

  • Fix: sometimes delta files picked by DeltaCompactionPicker not be used in compaction.
  • Fix: if nothing generated in a delta compaction, do not create a TSM file.
  • Optimize: improve performance of method DataBlock::merge() when merging a big data block with a small one.
  • Feature: Add config storage.enable_compaction

Are there any user-facing changes?
