morningman opened a new pull request #7656:
URL: https://github.com/apache/incubator-doris/pull/7656
## Proposed changes
1. Add a new FE config `colocate_group_relocate_delay_second`
The relocation of a colocation group may involve a large number of
tablets moving within the cluster.
Therefore, we should use a more conservative strategy to avoid
relocation of colocation groups as much as possible.
Reloaction usually occurs after a BE node goes offline or goes down.
This config is used to delay the determination of BE node unavailability.
The default is 30 minutes, i.e., if a BE node recovers within 30
minutes, relocation of the colocation group
will not be triggered.
2. Add a new FE config allow_replica_on_same_host
If set to true, when creating table, Doris will allow to locate replicas
of a tablet
on same host. And also the tablet repair and balance will be disabled.
This is only for local test, so that we can deploy multi BE on same host
and create table
with multi replicas.
