File Descriptors in Bitcoin Core
- We use leveldb for multiple databases: block index, chainstate and (optionally) txindex. block index is very small, but chainstate and txindex can grow to many hundreds of files.
- Each database has a limit on number of 'open files'. This limit includes both mmapped files (which ldb takes the fd for, opens and then closes, returning the fd) and files which ldb opens and holds the fd for. There's a default in the leveldb code here. This is the per-database max_open_files limit.

The Bitcoin Core wallet consists of:
- An in memory keystore (in /src/keystore.cpp), which contains:
- private keys stored as
mapKeys- a map from the CKeyID to the private key. - watchonly public keys, stored as
mapWatchKeys- a map from the CKeyID to the public key. - scripts, stored as
mapScripts- a map from the CScriptID to the secrialized script. - watchonly scripts, stored as
setWatch- a set of serialized scripts.
- private keys stored as
- Additional key metadata such as key birthday, hd derivation path. See
