Tsz-wo Sze commented on RATIS-2036:
-----------------------------------
[~tanxinyu], sure, we may pass a flag to decide if it is should trigger a
snapshot. Then, removeGroup can avoid taking a snapshot.

> Key: RATIS-2036
> URL: https://issues.apache.org/jira/browse/RATIS-2036
> Project: Ratis
> Issue Type: Improvement
> Components: server
> Reporter: Xinyu Tan
> Priority: Minor
>
> 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.
> What's your opinion? [~szetszwo]
