…/3.x docs Single replica compaction was removed in Doris 4.1.2 (apache/doris#63771) because its peer selection carries a data correctness risk: replicas pull compacted files based on periodically refreshed replica info while each replica advances through versions independently, so the selection can act on a stale view of the cluster and cause subtle data inconsistencies. Add deprecation notices to the compaction feature docs and the enable_single_replica_compaction property descriptions in 2.1 and 3.x, in both English and Chinese.
