BangDB vs MongoDB

BangDB: Converged C/C++ NoSQL platform mixing key-value, documents, time-series, stream processing, graph and ML. MongoDB: The default document database: flexible BSON documents, rich queries and built-in sharding.

key differences

  • Licensing: BangDB is proprietary (Proprietary (free binary download)); MongoDB is source-available (Server Side Public License v1 (Community); commercial (Enterprise)).
  • MongoDB is built for larger datasets (≤ 1 PB) than BangDB (≤ 10 TB).
  • Horizontal scaling is none in BangDB and native in MongoDB.
  • Transactions: BangDB offers limited ACID; MongoDB offers full.
  • Only BangDB has streaming ingest.
  • Only MongoDB has joins, full-text search, vector search, geospatial, change data capture.
  • BangDB can run embedded in your application process.
