Real time cross system database replication for hybrid cloud elastic scaling and high performance data virtualization

摘要

Problem to be solved: to provide real time cross land database database replication in a safe, automatic and accurate manner.Real time table replication of the database transaction to the replica table receives a replication and transaction commit log entry.The replication log entry has a row ID value, and the row of the replica table has a row ID value.The replication log entry is dispatched to the parallel logotype player, and the associated transaction commit log entry is dispatched to the transfer protocol logoplayer The reproduction log entry is replayed in the parallel log gripper based on the line ID value.The database transaction is then committed to the replica table by replaying the transaction commit log entry associated with the translation log player.Diagram
