--------------------------------
Summary: Avoid trigger snapshot when removing raftGroup
Key: RATIS-2036
URL: https://issues.apache.org/jira/browse/RATIS-2036
Project: Ratis
Issue Type: Improvement
Components: server
Reporter: Xinyu Tan
Currently, Ratis by default triggers a Snapshot of the state machine upon
stopping the service, which essentially increases the shutdown time but speeds
up the startup time. I've already raised a PR on this trade-off at
https://issues.apache.org/jira/browse/RATIS-1862 to allow configuration.
However, regardless of this configuration, for IoTDB's Delete Region, we hope
it can be deleted as soon as possible without triggering a snapshot, otherwise,
there might be some timeout issues. For Ratis, we wonder if it's necessary to
differentiate between a normal stop and removeGroup, thereby allowing
removeGroup to not trigger a snapshot, which may require an additional
parameter.
