[logback-dev] [JIRA] Commented: (LBCLASSIC-198) DBAppender: Support long event_id values in logging_event

[Michael Lynch]

It is mostly out of caution with some amount of fatalism mixed in.

We are working with a distributed databases that is synchronized back
to a central database.  In order to avoid key collisions we are
partitioning the key space.  We may have as many as 100 remote
databases - reducing the key space for any one to ~21million.

While I don't expect 21 million errors from a single instance (nor
even all together), there are processes that can run every few seconds
that can generate an error.  Left unchecked/unnoticed for long enough
and the volume of errors could add up over time.

In my experience there is very little memory or disk space issues
created by using a long instead of an int - although I recognize that
logback is used in many different ways/environments, so my experience
may not be as accurate in the context of logback.
