looks like this is limited by S3, is this a very large test?

Can we prevent the datanode from crashing? Should we trigger milvus rate limit, does it make sense?

@XuanYang-cn

@xiaocai2333 Many conditions can trigger a sync, for example 10mins cp sync, denying insertion won't fix the problem.

when reaching s3 rate limit, the best solution is just wait for s3 to recover, it's no difference whether dn crashes or dn online but unable to process any msgs.

need to change flush to async logic.
