Maysam Yabandeh 199fabc197 WritePrepared: non-atomic commit of delayed prepared (#4947) ... Summary: Commit of delayed prepared has two non-atomic steps: add to commit cache, remove from delayed_prepared_. Similarly in ::IsInSnapshot we read from commit cache first and then look into delayed_prepared_. Due to non-atomicity thus the reader might not find the prep_seq that is just committed neither in commit cache nor in delayed_prepared_. To fix that i) we check if there was any delayed prepared BEFORE looking into commit cache, ii) if there was, we complete the search steps to be these: i) commit cache, ii) delayed prepared, commit cache again. In this way if the first query to commit cache missed the commit, the 2nd will catch it. The cost of the redundant read from commit cache is paid only if delayed_prepared_ is nonempty which should be a very rare scenario.
