liveDiskSpaceUsed and totalDiskSpaceUsed get corrupted if IndexSummaryRedistribution gets interrupted

    XMLWordPrintableJSON

Details

    Description

      IndexSummaryRedistribution is a compaction task and as such extends Holder and supports cancelation by throwing a CompactionInterruptedException. The issue is that IndexSummaryRedistribution tries to use transactions, but mutates the sstable in-place; transaction is unable to roll back.

      This would be fine (only updates summary) if it wasn’t for the fact the task attempts to also mutate the two metrics liveDiskSpaceUsed and totalDiskSpaceUsed, since these can’t be rolled back any cancelation could corrupt these metrics.
