Abstract: Disclosed herein are system, method, and computer program product embodiments for replication of database. In one embodiment, one or more data pages generated from a transaction are obtained at a first node. The one or more data pages are compressed. The compressed data pages are added into a first queue in a memory of the first node. The first queue includes a plurality of blocks. A first block of the compressed data pages in the first queue is transmitted to a second node when the first block of the compressed data pages becomes available for replication. The first block of the compressed data pages is stored in a persistent storage of the first node.
