Subject [jira] [Commented] (CASSANDRA-9054) Break DatabaseDescriptor up into multiple classes.
Date Sun, 17 Apr 2016 09:25:25 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-9054?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15244591#comment-15244591

Robert Stupp commented on CASSANDRA-9054:
-----------------------------------------

Uh - this will be a noisy patch.

At least I managed to pull out everything from DatabaseDescriptor that initializes something
during class initialization.
Good thing is, it's nothing complicated - just "boring" stuff, just a huge amount of boring
stuff to add initialization to unit tests.

> Right now to get at Config stuff you go through DatabaseDescriptor.  But when you instantiate
DatabaseDescriptor it actually opens system tables and such, which triggers commit log replays,
and other things if the right flags aren't set ahead of time.  This makes getting at config
stuff from tools annoying, as you have to be very careful about instantiation orders.
> It would be nice if we could break DatabaseDescriptor up into multiple classes, so that
getting at config stuff from tools wasn't such a pain.
