Does JRaft guarantee idempotency? #1053

When I send a write request it times out and does a retransmit (network packet loss may have occurred). Will the write be performed 2 times at this point?

sofajraft doesn't guarantee idempotency. Generally, this can be solved at the upper layer. The client can carry a unique id , and the your own stat-machine can make idempotent decisions based on this id.

As Jiachun said, it's not the issue that jraft or raft algorithm tries to address.
