Will there be any issue efficiency wise or any other issue if for every sync I create a new connection, perform a sync, and then delete the connection. The thing is in the destination side the schema is changing according to the source if I do something like this.

Hi @Shubham Pinjwani do you mean this could be a workaround for you to handle source schema change? If you're using full refresh sync it can work but I don't think it's the best approach to take. I'd rather suggest you leverage our API to automatically reset the data for the connection, rerun a schema discovery on the source and then update the connection with the discovered schema (or accomplish this actions manually if you don't want to script anythin). Feel free to post on our Discourse forum if you want to continue this conversation with the community, we're moving our support to this platform soon.
