Strengths and trade-offs
RocksDB — where it wins
- 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
Where it doesn't
- Replication is not built in and requires application-built logic
- The API query interface is focused on key-value access
- It is an embeddable C++ library rather than a hosted product
PouchDB — where it wins
- Stores schemaless JSON documents locally in browsers and Node.js
- Supports bidirectional replication with CouchDB-compatible servers
- Includes attachments, querying, indexing, and changes feeds
Where it doesn't
- Does not provide transactions
- Is not a vendor-operated managed cloud database
- Remote synchronization depends on CouchDB-compatible services
- RocksDB—/10 · Open source
A focused open-source engine for high-throughput embedded key-value workloads.
