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.

Selective forwarding for multi-statement database transactions

Automatic consistency is implemented for forwarding writes in a database system. A read-only node may support both read and write requests to a database. The read only node may forward write requests to a read-write node. The read-only node may determine whether to include the forwarded requests in a version of the database for a read request automatically according to a consistency specified for a read request.

Automatic consistency for database write forwarding

This application relates to multi-level replication filtering for a distributed database. A primary node of the database can generate log records that describe write requests performed to the database. The primary node can, in some embodiments, identify a portion of the data of the database that is stored at a second node, such as data stored by a read replica node that can be used in responding to read requests from clients. The primary node can select log records that are applicable to this identified portion of the data to send to the second node. Log records are not selected based on a determination that those unselected log records are not applicable to the identified portion of the data. The primary node can then send the selected log records to the second node, for the second node to apply the log records to its stored database data.
