That "3x" number is just an approximation. Depending on your settings and content it could be anywhere from 0.5x (yes, smaller than the original) to... maybe 8x? Given that you can create as many fields as you like, there may be no upper limit.
The database size is the total size on disk. I'm not sure about active merges, but merge space in general isn't included, and really ought to be up to 3x the size of the fully-merged database. That's because you may sometimes need to reindex the whole database, and during that process you are likely to reach a point where you have N deleted fragments, N fragments, and need a full merge to clean out the deleted fragments. The best way to find out how large your database will actually be is to prototype. Load a significant fraction of your content in a single forest, maybe 1-5% of what you expect to have per host, and develop your core queries. Make any adjustments to the index configuration, then merge the forest to one stand. Use that on-disk size to project the final size. -- Mike On 18 Jan 2013, at 05:28 , "Chowdhury, Soumadri" <[email protected]> wrote: > Hi, > > Can anyone help me understand how much the DB size can grow?
