morningman opened a new pull request #7647:
URL: https://github.com/apache/incubator-doris/pull/7647
## Proposed changes
Currently, if we encounter a problem with a replica of a tablet during the
load process,
such as a write error, rpc error, -235, etc., it will cause the entire load
job to fail,
which results in a significant reduction in Doris' fault tolerance.
This PR mainly changes:
1. refined the judgment of failed replicas in the load process, so that the
failure of a few replicas will not affect the normal completion of the load job.
2. added a new fe parameter: `colocate_group_relocate_delay_second`
This parameter is used to delay triggering the redistribution of
colocation group.
3. lowered the clone task priority of colocation relocate from HIGH to NORMAL
4. added some debugging documentation on replica repair and balancing
