Azat Khuzhin e148ef739d Drop replicas from dirname for internal_replication=true ... Under use_compact_format_in_distributed_parts_names=1 and internal_replication=true the server encodes all replicas for the directory name for async INSERT into Distributed, and the directory name looks like: shard1_replica1,shard1_replica2,shard3_replica3 This is required for creating connections (to specific replicas only), but in case of internal_replication=true, this can be avoided, since this path will always includes all replicas. This patch replaces all replicas with "_all_replicas" marker. Note, that initial problem was that this path may overflow the NAME_MAX if you will have more then 15 replicas, and the server will fail to create the directory. Also note, that changed directory name should not be a problem, since: - empty directories will be removed since #16729 - and replicas encoded in the directory name is also supported anyway.		2021-06-23 02:47:38 +03:00
