Events related to transactions, can span across multiple databases. > When a transaction does some write operation, it is added to the write > notification log table. During dump of commit transaction event, al the > entries present in the write notification log table for that transaction is > read and is added to the commit transaction message. In case partition filter > is supplied for the dump, only those partitions which are part of the policy > should be added to the commit txn message. > * All the events which are not partition level will be added to the list of > events to be dumped. > * Pass the filter condition for the policy to commit transaction message > handler (events which are not partition level). > * During dump for commit transaction event, extract the events added in the > write notification log table and compare it with the filter condition. > * If the event from write notification log satisfies the filter condition, > then add it to the commit transaction message. > * If filter condition is null, then add all the events from write > notification log table to commit transaction message. > * For events which does not have partition level info like open txn, abort > txn etc, just dump the events without any filtering. So it may happen that > some of events which are not related to any of the satisfying partition, may > get replayed. -- This message was sent by Atlassian Jira (v8.20.10#820010)
