Abstract: Disclosed herein are system, method, and computer readable device embodiments for parallel replication of databases across row-store and column-store table formats. An embodiment operates by maintaining a replication log and a storage-level recovery log formatted according to separate respective log formats, logging a record-level SQL execution result, and replicating at least one database table from a primary server to at least one replica server. The primary server and the at least one replica server may each be configured to store data according to one table format of a row-store table format and a column-store table format, such that the primary server's table format is different from the at least one replica server's table format.
