I just wanted to make you all aware of a new KB article myself and a couple of teammates put together around component store growth and remediation. I wanted to have something short and to the point and I think a lot of you might find this more useful than sifting through the blog trying to piecemeal together the same information. I'll probably try to put together something a little more verbose here that goes more into the internals of some of this but I am busy working on a new project and dont have tons of time. If you have any questions or comments about the material please ask them here.
