Abstract

Transaction statements may be forwarded for a database transaction. A transaction begun at a read-only node may include a write statement. The read-only node may forward the write statement to the read-only node to perform as a transaction. The read-only node may update a read view for the transaction to include the write statement before performing a read statement submitted after the write statement at the read-only node.
