Tracks gaps in transaction ids when replicating from SQL to datastore.
SQL -> DS replication uses a Transaction table indexed by a SEQUENCE column, which normally increments monotonically for each committed transaction. Gaps in this sequence can occur when a transaction is rolled back or when a transaction has been initiated but not committed to the table at the time of a query. To protect us from the latter scenario, we need to keep track of these gaps and replay any of them that have been filled in since we processed their batch.
