This PR adds a deferrable option to the SQLExecuteQueryOperator. I have also created a SQLExecuteQueryTrigger and DbApiHookAsync for this.

Closes: #30451

We are also interested in having a deferable SQL operator, thanks a lot for this great work @karenbraganz . What is the plan for the next steps for this PR? I think this is a very important and nice addition to Airflow.

Hi,

I am currently working on making this compatible with different database types:
Postgres
MySQL/MariaDB
SQLite
Oracle
MS SQL
Redshift
Snowflake

@kullanici0606 which database type are you planning to use this with? I can try to prioritize compatibility for that type during development.

Hi @karenbraganz

That would be great, thanks a lot. We are using SQLExecuteQueryOperator with mostly Oracle and also with Postgresql.

Providing an update: I have created a deferrable version of the SqlExecuteQueryOperator on this PR. I had to refactor a lot of code, so I ended up creating a new PR. I will close this PR.
