Best Practice For Broker

Some useful tips for users.

Broker Role

Broker Role is ASYNC_MASTER, SYNC_MASTER or SLAVE. If you cannot tolerate message missing, we suggest you deploy SYNC_MASTER and attach a SLAVE to it. If you feel ok about missing, but you want the Broker to be always available, you may deploy ASYNC_MASTER with SLAVE. If you just want to make it easy, you may only need a ASYNC_MASTER without SLAVE.

FlushDiskType

ASYNC_FLUSH is recommended, for SYNC_FLUSH is expensive and will cause too much performance loss. If you want reliability, we recommend you use SYNC_MASTER with SLAVE.
