Abstract
A method may include responding to a transaction by sending, to a first data partition participating in the transaction, a first request to set a first transaction control block at the first data partition to a preparing state. In response to the transaction affecting multiple data partitions, a second request to set a second transaction control block at a second data partition to the preparing state may be sent to the second data partition. A third request to add the first data partition and the second data partition as participants of the transaction may be sent to the transaction coordinator. The transaction coordinator may determine, based on a first response of the first data partition and a second response of the second data partition, an outcome of the transaction. The transaction may be rolled back if the first response and/or the second response indicate an inability to commit the transaction.
