I am looking for ideas on how to keep my app running all the time, even when uploading data that will replace the current data. Some of these tables will have a million rows or more. Ideas?
Almost a question for the PostgreSQL users list - assuming that is your DBMS. It will depend on so many aspects of what is actually happening during/after upload.
In theory, if you upload data in a single transaction - or even many transactions - there will be no impact on users until the moment of committing.
In practice, theory might be inadequate.
