> h1. Replicate ACID write Events
> * Create new EVENT_WRITE event with related message format to log the write
> operations with in a txn along with data associated.
> * Log this event when perform any writes (insert into, insert overwrite,
> load table, delete, update, merge, truncate) on table/partition.
> * If a single MERGE/UPDATE/INSERT/DELETE statement operates on multiple
> partitions, then need to log one event per partition.
> * DbNotificationListener should log this type of event to special metastore
> table named "MTxnWriteNotificationLog".
> * This table should maintain a map of txn ID against list of
> tables/partitions written by given txn.
> * The entry for a given txn should be removed by the cleaner thread that
> removes the expired events from EventNotificationTable.
> h1. Replicate Commit Txn operation (with writes)
> Add new EVENT_COMMIT_TXN to log the metadata/data of all tables/partitions
> modified within the txn.
> *Source warehouse:*
> * This event should read the EVENT_WRITEs from "MTxnWriteNotificationLog"
> metastore table to consolidate the list of tables/partitions modified within
> this txn scope.
> * Based on the list of tables/partitions modified and table Write ID, need
> to compute the list of delta files added by this txn.
> * Repl dump should read this message and dump the metadata and delta files
> list.
> *Target warehouse:*
> * Ensure snapshot isolation at target for on-going read txns which shouldn't
> view the data replicated from committed txn. (Ensured with open and allocate
> write ID events).
