Policy summary
The master and slave nodes are mutually standby, with no read/write splitting. The slave database is only synchronous and does not provide external services. The master database has no persistence policy, and the backup database uses
Recently, a project uses the open-source key-value storage redis server, which was proposed by colleagues.
One master is deployed and several slave instances are deployed. Slave and master are synchronized.
After development, go online. The next day,
