What’s the relationship between LevelDB’s cache (default 8MB) and Bitcoin’s UTXO cache?


Please right me if I’m incorrect.
Bitcoin makes use of levelDB to retailer UTXO set. LevelDB has a default 8MB block cache, and the Bitcoin additionally has a dbcache(default 450MB).

  1. What’s the relationship between the 2?
  2. Which a part of the Bitcoin system does the levelDB’s block cache correspond to?
