 DB Audit Degrade Performance? |
 |
My DB Audit database got about 40G data after implemeting for a year.
And it is found that database has slow response.
In my concept, DB Audit uses trigger to record INSERT/UPDATE/DELETE, which performance should not be affected by the size of DB Audit database, right?
Or DB Audit trigger actually do some "select" action before / after inserting audit record?

The size of the database is not important for the performance if it is not very fragmented and the database server does not spend a lot of time searching for where to save the new data.

It may read filter definitions, if any filters have been defined. That's all. If filters have been defined reasonable, that read is nothing in terms of performance impact, it should be all cached in memory
