Abstract
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.
