WT keeps all the collection and index files open - how to avoid that


My setup contains many collections and indexes (ca. 200’000) and it turns out that during the startup, WT opens the files and keeps them open.

As you can imagine that uses up quite some memory - just the buffer uses up ca. 6 GB.

Question : what if the total amount of RAM would be just 4GB - would WT keep less files open ?

Thanks & Regards
