From 4d387e62788483acebe37a00ca6122ad2c4198ec Mon Sep 17 00:00:00 2001 From: Hou Zhijie Date: Mon, 24 Apr 2023 19:27:23 +0800 Subject: [PATCH 5/8] DDL replication for Table DDL commands OVERVIEW -------- To support DDL replication, we use the event trigger and DDL deparsing facilities. During CREATE PUBLICATION we register a 'command end' trigger that deparses the DDL (if the DDL is annotated as ddlreplok for DDL replication in cmdtaglist.h) as a JSON blob, and WAL logs it. The event trigger is automatically removed at the time of DROP PUBLICATION. The WALSender decodes the WAL and sends it downstream similar to other DML commands. The subscriber then converts JSON back to the DDL command string and executes it. In the subscriber, we also add the newly added rel to pg_subscription_rel so that the DML changes on the new table can be replicated without having to manually run "ALTER SUBSCRIPTION ... REFRESH PUBLICATION". For non-rewrite ALTER object command and CREATE object command: --------------------------------------------------------------- We deparse the command at ddl_command_end event trigger and WAL log the deparsed json string. The WALSender decodes the WAL and sends it to subscriber if the created/altered table is published. It supports most of ALTER TABLE command except some commands(DDL related to PARTITIONED TABLE ...) that are recently introduced but are not yet supported by the current ddl_deparser, we will support that later. For DROP object: ---------------- The 'command start' event handler logs a ddl message with the relids of the tables that are dropped which the output plugin (pgoutput) stores in its internal data structure after verifying that it is for a table that is part of the publication. Later the 'command end' event handler sends the actual drop message. On receiving the 'command end', pgoutput sends the DROP command only if it is for one of the relids marked for deletion. The reason we have to do this is because, once the logical decoder receives the 'command end' message, the relid of the table is no longer valid as it has been deleted as part of invalidations received for the drop table command. It is no longer possible to verify if the table is part of the publication list or not. To make this possible, two more elements are added to the ddl xlog and ddl message, (relid and cmdtype). We could have also handled all this on the subscriber side, but that would mean sending spurious ddl messages for tables that are not part of the publication. For table_rewrite ALTER TABLE command: -------------------------------------- Executing a non-immutable expression during the table rewrite phase is not allowed, as it may result in different data between publisher and subscriber. While some may suggest converting the rewrite inserts to updates and replicate them afte the ddl command to maintain data consistency. But it doesn't work if the replica identity column is altered in the command. This is because the rewrite inserts do not contain the old values and therefore cannot be converted to update. LIMIT: Commands contain volatile functions are not allowed. Because it's possible the functions contain DDL/DML in which case these operations will be executed twice and cause duplicate data. In addition, we don't know whether the tables being accessed by these DDL/DML are published or not. So blindly allowing such functions can allow unintended clauses like the tables accessed in those functions may not even exist on the subscriber. --- contrib/test_decoding/expected/ddl.out | 26 + contrib/test_decoding/sql/ddl.sql | 5 + contrib/test_decoding/test_decoding.c | 48 + doc/src/sgml/catalogs.sgml | 9 + doc/src/sgml/logical-replication.sgml | 1093 +++++++++++++++++ src/backend/access/rmgrdesc/Makefile | 1 + .../access/rmgrdesc/logicalddlmsgdesc.c | 52 + src/backend/access/rmgrdesc/meson.build | 1 + src/backend/access/transam/rmgr.c | 1 + src/backend/catalog/pg_publication.c | 1 + src/backend/commands/alter.c | 17 + src/backend/commands/ddldeparse.c | 96 +- src/backend/commands/event_trigger.c | 37 +- src/backend/commands/publicationcmds.c | 238 +++- src/backend/replication/logical/Makefile | 2 + src/backend/replication/logical/ddlmessage.c | 83 ++ src/backend/replication/logical/ddltrigger.c | 341 +++++ src/backend/replication/logical/decode.c | 41 + src/backend/replication/logical/logical.c | 97 +- .../replication/logical/logicalfuncs.c | 24 + src/backend/replication/logical/meson.build | 2 + src/backend/replication/logical/proto.c | 43 + .../replication/logical/reorderbuffer.c | 135 ++ src/backend/replication/logical/worker.c | 237 ++++ src/backend/replication/pgoutput/pgoutput.c | 166 ++- src/backend/tcop/cmdtag.c | 26 +- src/backend/tcop/utility.c | 2 +- src/backend/utils/cache/relcache.c | 1 + src/bin/pg_dump/pg_dump.c | 26 +- src/bin/pg_dump/pg_dump.h | 1 + src/bin/pg_dump/t/002_pg_dump.pl | 2 +- src/bin/pg_waldump/.gitignore | 1 + src/bin/pg_waldump/rmgrdesc.c | 1 + src/bin/psql/describe.c | 17 +- src/include/access/rmgrlist.h | 1 + src/include/catalog/pg_event_trigger.h | 2 +- src/include/catalog/pg_proc.dat | 20 + src/include/catalog/pg_publication.h | 30 +- src/include/commands/event_trigger.h | 2 +- src/include/commands/publicationcmds.h | 14 + src/include/replication/ddlmessage.h | 60 + src/include/replication/decode.h | 1 + src/include/replication/logicalproto.h | 4 + src/include/replication/output_plugin.h | 27 + src/include/replication/pgoutput.h | 1 + src/include/replication/reorderbuffer.h | 39 + src/include/tcop/cmdtag.h | 4 +- src/include/tcop/cmdtaglist.h | 386 +++--- src/include/tcop/ddldeparse.h | 10 +- src/include/utils/rel.h | 2 + src/test/regress/expected/psql.out | 6 +- src/test/regress/expected/publication.out | 420 +++---- src/tools/pgindent/typedefs.list | 6 + 53 files changed, 3432 insertions(+), 476 deletions(-) create mode 100644 src/backend/access/rmgrdesc/logicalddlmsgdesc.c create mode 100644 src/backend/replication/logical/ddlmessage.c create mode 100644 src/backend/replication/logical/ddltrigger.c create mode 100644 src/include/replication/ddlmessage.h diff --git a/contrib/test_decoding/expected/ddl.out b/contrib/test_decoding/expected/ddl.out index d55fb3a667..f4173f0497 100644 --- a/contrib/test_decoding/expected/ddl.out +++ b/contrib/test_decoding/expected/ddl.out @@ -831,6 +831,32 @@ SELECT data FROM pg_logical_slot_get_changes('regression_slot', NULL, NULL, 'inc ------ (0 rows) +SELECT 'ddl msg1' FROM pg_logical_emit_ddl_message('ddl msg1', 16394, 1, 'msg1');

+ + + + DDL Deparser + + The DDL deparser utility is invoked during the replication of DDLs.
