Abstract
Aspects of the disclosure are directed to a parallel recovery mode that applies log records while allowing read queries on read-replica databases. The parallel recovery mode can include applying log records in log sequence number (LSN) order for a block or for multiple blocks, and managing log records affecting multiple blocks. The parallel recovery mode can further manage dependency between different log records and maintain transactional consistency on read queries.
