Abstract :
Data synchronization based on virtual log is now widely used, while huge log records will affect the efficiency of data synchronization, especially when the master side has frequent changes in same record. Virtual log compression will calculate and merge log records, and only those records related with data synchronization will be left and therefore reducing network traffic and improve the efficiency of data synchronization. Virtual log compression is particularly suitable for heterogeneous database and asynchronous data synchronization in WAN, and has a high prospect.
