Re: Track all records read from a table

As I understand it, a read trigger is pulled with CPYF and normal back-up. That could be a serious impact on some files and would be a big concern that should not be ignored. In my opinion.

Excellent point. (I do think you meant firing trigger rather than
journaling will slow it down though)

Additionally to mitigate the effect of the trigger, when your read trigger
fires, have it do nothing but enqueue a data queue entry with the needed
information then quit. That way it's very fast, and any database activity
would not be impacted. Your program that reads the data queue and does
whatever it has to do can then do it in a more leisurely way.
