Currently, the system.compaction_history table miss precious information like the type of compaction (cleanup, major, resharding, etc) or the sstable generations involved (in and out) used countless times to diagnose issues. Thus, the commit extend the current definition of the table by adding the following columns: + "compaction_type" (text) + "started_at" (int) + "shard_id" (int) + "sstables_in" (list<sstableinfo_type>) + "sstables_out" (list<sstableinfo_type>) + "total_tombstone_purge_attempt" (long) + "total_tombstone_purge_failure_due_to_overlapping_with_memtable" (long) + "total_tombstone_purge_failure_due_to_overlapping_with_uncompacting_sstable" (long) Furthermore, the commit introduces a new feature flag in order to prevent nodes from writing data to new columns when a cluster is not fully upgraded.
