In order to assist our users with WT cache sizing, we need a way to gather information about memory pages currently in the cache, specifically which namespaces/indexes they belong to and their size, so that a working set estimation can be performed, e.g.:
"test.test" : {
cached_pages: 54
cached_size: 23456
},
"test.test._id_" : {
cached_pages: 5
cached_size: 1234
}
This statistic can be approximate and I think it only needs to be executed ad-hoc, but it must not noticeably disrupt ongoing database operations.
