Hi, I am looking to validate a table in the database with the help of the transformed table which I already created through meltano, so is there any way to integrate this validation in meltano pipeline and also can I do alerting on that.

This is not something Meltano currently does, which falls into the Data Testing process. It is something we have on our radar but I don't expect we work on that in the near future. Please open an issue with you feature suggestion so we can prioritize and we'll see what we can do.
