With a transaction batch, multiple transactions from the log can be returned as a single transaction. If the logged transactions are being fed into another database, batching transactions can improve write performance over the network. For example, a number of inserts can be batched in one transaction so that when the inserts are applied to another database, only one transaction needs to be executed.

Set the transaction batch size by using the SET REPLICATION BATCH statement, see SET REPLICATION BATCH.

The default batch size is 1, which means that no batching of transactions is done.
