Pros
  • Point lookups and range scans for byte-stream keys and values
  • Multi-threaded compactions with configurable compression and storage options
  • Backup, checkpoint, snapshot, and database-management APIs
  • Stores schemaless JSON documents locally in browsers and Node.js
  • Supports bidirectional replication with CouchDB-compatible servers
