[PATCH] Asymmetric partitionwise join. 142+ messages / 2 participants [nested] [flat]
* [PATCH] Asymmetric partitionwise join. @ 2021-04-02 06:02 Andrey Lepikhov <[email protected]> 0 siblings, 0 replies; 142+ messages in thread From: Andrey Lepikhov @ 2021-04-02 06:02 UTC (permalink / raw) Teach optimizer to consider partitionwise join of non-partitioned table with each partition of partitioned table. Disallow asymmetric machinery for joining of two partitioned (or appended) relations because it could cause huge consumption of CPU and memory during reparameterization of NestLoop path. Change logic of the multilevel child relids adjustment, because this feature allows the optimizer to plan in new way. --- src/backend/optimizer/path/joinpath.c | 9 + src/backend/optimizer/path/joinrels.c | 187 +++++++++ src/backend/optimizer/plan/setrefs.c | 17 +- src/backend/optimizer/util/appendinfo.c | 51 ++- src/backend/optimizer/util/pathnode.c | 9 +- src/backend/optimizer/util/relnode.c | 19 +- src/include/optimizer/paths.h | 7 +- src/test/regress/expected/partition_join.out | 378 +++++++++++++++++++ src/test/regress/sql/partition_join.sql | 167 ++++++++ 9 files changed, 808 insertions(+), 36 deletions(-) diff --git a/src/backend/optimizer/path/joinpath.c b/src/backend/optimizer/path/joinpath.c index 6407ede12a..32618ebbd5 100644 --- a/src/backend/optimizer/path/joinpath.c +++ b/src/backend/optimizer/path/joinpath.c @@ -335,6 +335,15 @@ add_paths_to_joinrel(PlannerInfo *root, if (set_join_pathlist_hook) set_join_pathlist_hook(root, joinrel, outerrel, innerrel, jointype, &extra); + + /* + * 7.

* [PATCH] Asymmetric partitionwise join. @ 2021-04-02 06:02 Andrey Lepikhov <[email protected]> 0 siblings, 0 replies; 142+ messages in thread From: Andrey Lepikhov @ 2021-04-02 06:02 UTC (permalink / raw) Teach optimizer to consider partitionwise join of non-partitioned table with each partition of partitioned table. Disallow asymmetric machinery for joining of two partitioned (or appended) relations because it could cause huge consumption of CPU and memory during reparameterization of NestLoop path. Change logic of the multilevel child relids adjustment, because this feature allows the optimizer to plan in new way. --- src/backend/optimizer/path/joinpath.c | 9 + src/backend/optimizer/path/joinrels.c | 187 ++++++++ src/backend/optimizer/plan/setrefs.c | 17 +- src/backend/optimizer/util/appendinfo.c | 44 +- src/backend/optimizer/util/pathnode.c | 9 +- src/backend/optimizer/util/relnode.c | 19 +- src/include/optimizer/paths.h | 7 +- src/test/regress/expected/partition_join.out | 425 +++++++++++++++++++ src/test/regress/sql/partition_join.sql | 180 ++++++++ 9 files changed, 867 insertions(+), 30 deletions(-) diff --git a/src/backend/optimizer/path/joinpath.c b/src/backend/optimizer/path/joinpath.c index 6407ede12a..32618ebbd5 100644 --- a/src/backend/optimizer/path/joinpath.c +++ b/src/backend/optimizer/path/joinpath.c @@ -335,6 +335,15 @@ add_paths_to_joinrel(PlannerInfo *root, if (set_join_pathlist_hook) set_join_pathlist_hook(root, joinrel, outerrel, innerrel, jointype, &extra); + + /* + * 7.

* [PATCH 5/6] Use background worker to do logical decoding. @ 2026-01-22 08:23 Antonin Houska <[email protected]> 0 siblings, 0 replies; 142+ messages in thread From: Antonin Houska @ 2026-01-22 08:23 UTC (permalink / raw) If the backend performing REPACK (CONCURRENTLY) does both data copying and logical decoding, it has to "travel in time" back and forth and therefore it has to invalidate system caches quite a few times. (The copying and the decoding work with different catalog snapshots.) As the decoding worker has separate caches, the switching is not necessary. Without the worker, it'd also be difficult to switch between potentially long running tasks like index build and WAL decoding. (No decoding during that time at all can suspend archiving / recycling of WAL segments for some time, which in turn may result in full disk.) Another problem is that, after having acquired AccessExclusiveLock (in order to swap the files), the backend needs to both decode and apply the data changes that took place while it was waiting for the lock. With the decoding worker, the decoding runs all the time, so the backend only needs to apply the changes. This can reduce the time the exclusive lock is held for. Note that the code added in order to handle ERRORs in the background worker almost duplicates the existing code that does the same for other types of workers (See ProcessParallelMessages() and ProcessParallelApplyMessages()). Refactoring of the existing code might be useful, to reduce the duplication. --- src/backend/access/heap/heapam_handler.c | 44 - src/backend/commands/cluster.c | 1179 +++++++++++++---- src/backend/libpq/pqmq.c | 5 + src/backend/postmaster/bgworker.c | 4 + src/backend/replication/logical/logical.c | 6 +- .../pgoutput_repack/pgoutput_repack.c | 54 +- src/backend/storage/ipc/procsignal.c | 4 + src/backend/tcop/postgres.c | 4 + .../utils/activity/wait_event_names.txt | 1 + src/include/access/tableam.h | 7 +- src/include/commands/cluster.h | 71 +- src/include/storage/procsignal.h | 1 + src/tools/pgindent/typedefs.list | 3 +- 13 files changed, 981 insertions(+), 402 deletions(-) diff --git a/src/backend/access/heap/heapam_handler.c b/src/backend/access/heap/heapam_handler.c index 908f1ef66c6..8589b3c940e 100644 --- a/src/backend/access/heap/heapam_handler.c +++ b/src/backend/access/heap/heapam_handler.c @@ -33,7 +33,6 @@ #include "catalog/index.h" #include "catalog/storage.h" #include "catalog/storage_xlog.h" -#include "commands/cluster.h" #include "commands/progress.h" #include "executor/executor.h" #include "miscadmin.h" @@ -688,7 +687,6 @@ heapam_relation_copy_for_cluster(Relation OldHeap, Relation NewHeap, Relation OldIndex, bool use_sort, TransactionId OldestXmin, Snapshot snapshot, - LogicalDecodingContext *decoding_ctx, TransactionId *xid_cutoff, MultiXactId *multi_cutoff, double *num_tuples, @@ -710,7 +708,6 @@ heapam_relation_copy_for_cluster(Relation OldHeap, Relation NewHeap, BufferHeapTupleTableSlot *hslot; BlockNumber prev_cblock = InvalidBlockNumber; bool concurrent = snapshot != NULL; - XLogRecPtr end_of_wal_prev = GetFlushRecPtr(NULL); /* Remember if it's a system catalog */ is_system_catalog = IsSystemRelation(OldHeap); @@ -971,31 +968,6 @@ heapam_relation_copy_for_cluster(Relation OldHeap, Relation NewHeap, ct_val[1] = *num_tuples; pgstat_progress_update_multi_param(2, ct_index, ct_val); } - - /* - * Process the WAL produced by the load, as well as by other - * transactions, so that the replication slot can advance and WAL does - * not pile up.
