Insert Record From Memory -- What Happens if Record Exists?
Does the Insert Record From Memory option update existing records, or is it strictly an insertion tool?

I have a big backlog of data to load into a new table and may want to use this just for the first pull, or I may want to continue to use it for updates since there is a need to have a fifteen day redundancy on the updates each night. Will Insert Record From Memory crash if the record already exists?

Dear John,
The underlying database will return error messages. It will not crash but give a message for each duplicate record. Depending on your property settings in the DM flow it will stop/crash after ### DBMS errors.
Even you do not mind these errors it will seriously slow down the insert because of the enormous amount of messages that need to be processed.

Furthermore, Insert Records from Memory, as the name implies is an insert only operation. If you need to updates use load type insert/update.
