A bug could happen in transactional reads when the hybrid time is assigned at the YQL node and not on the tablet itself. To fix this:

  • Retain a longer history by default (a few seconds).
  • Reject requests that have the hybrid time older than the current history cutoff that could have already been garbage collected.
