### Valid file sets

Only files that are part of a valid file set will be processed by sonargd. A valid file set is a group of files with the same timestamp in their name, that was fully copied into the system.

Files with SESSION, SESSION_END and FULL_SQL in their names require session id to be processed, and thus must be processed together, or not at all.

With the exception of files with SESSION, SESSION_END and FULL_SQL in their names, all files that arrive are processed immediately. These files need to be processed together; the system will wait for all of them to arrive before processing.
