Re: LMDB : mdb_drop is slow

I have a lmdb environment in linux with 4K (MDB_dbi) databases. The size

foreach (MDB_dbi db in databases)
mdb_drop (txn, db, 0);
This process takes more that 10 hours. Is it reasonable ?
Probably not a reasonable thing to do. Just delete the DB file and
recreate it. mdb_drop() is only slightly faster than mdb_delete'ing each
