tablets moving within the cluster.

relocation of colocation groups as much as possible.

+ * This parameter is used to delay the determination of BE node
unavailability.

minutes, relocation of the colocation group

+ * 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.
+ * DO NOT use it for formal env.
