      Description

      There is a data race in the rollback log found when running hotindexer-bw test with the thread sanitizer. The problem is caused when an indexer thread and a client thread were simultaneously updating the same transaction rollback log. There is a case where the rollback log is not locked with the transaction lock, which caused the data race to be discovered.
