Is it easily possible to access the id2e sub-DB and query number of entries?

Something like

mdb_stat -s id2e -e <db-path> | grep Entries

but from Python with python-lmdb or a similar module.

It's pretty trivial in py-lmdb.

#### import lmdb

env = lmdb.open('/tmp/test', max_dbs=2) with env.begin() as txn: subdb = env.open_db('id2e', txn=txn, create=False) print txn.stat(subdb) ####

Thanks Howard!

Just for the records: With Python3 one has to pass the name of the sub-DB as byte-string.

subdb = env.open_db(b'id2e', txn=txn, create=False)
