BDR is significantly different to standalone PostgreSQL when it comes to DDL replication, and treating it as the same is the most common operational issue with BDR. The main difference from table replication is that DDL replication does not replicate the result of the DDL, but the statement its...
1.trigger记录ddl操作本身效率不高 2.如果某个库不能访问存储ddl操作的表的数据库,将导致该数据库所有ddl操作hang住,从而可能使得该数据库hang住的风险.
If the value isfalse, pgl_ddl_deploy will only auto-replicate a client SQL statement containing one command tag that matches the event trigger command tag. That is really safe, but it means you may have a lot more unhandled deployments. ...
PL/SQL, developed by Oracle Corporation, is a procedural extension to SQL. It is primarily used with the Oracle Database. PL/SQL allows developers to write stored procedures, functions, and triggers, making it a powerful choice for building complex applications within the Oracle environment. ...
It relies on SQL triggers that will populate a Postgres table (pgstream.schema_log) containing a history log of all DDL changes for a given schema. Whenever a schema change occurs, this trigger creates a new row in the schema log table with the schema encoded as a JSON value. This ...
