Database replication and partition<! –more–>

##Separate/dismantle inventory
Partition is applied to partition orthogonal business domains into different databases

##Copy
Use replication together with loader balance. There are two ways: synchronous and asynchronous.

  • Synchoronus

The internet speed requirement is relatively fast, and it is used in critical business areas such as finance. Different nodes backup and partition each other

  • Asynchoronous

Asynchronous use Queue and Pub/Sub methods. Application scenarios include shredder recovery and slow internet speeds
