Incremental updates to user transaction state at read-only nodes of a distributed database

摘要

A distributed database system may implement incremental updates to user transaction state at read-only nodes of the distributed database. A read-write node of the distributed database may determine a change to transaction state for a user transaction initiated at the read-write node. The read-write node may send a notification of the change to the transaction state for the user transaction to a read-only node in order to incrementally update the transaction state for the user transaction at the read-only node. The read-only node may receive the notification of the change to the transaction state and update in-memory system metadata to apply the change to the transaction state for the user transaction. A view of the distributed database may be made available at the read-only node for read requests according to the updated transaction state for the user transaction.
