I have a mongodb database with about 2 billion records, shared between 20 or so collections. Each of these collections has an index on it, based on a single key (other than _id).
I have an index file (named index-1-5374774422504609475.wt) that I'd like to match to a collection. Is there a quick way to match directly which index file corresponds to a collection?
I do mean the actual physical index file in the mongo db directory.
Thanks in advance!
