AsterixDB: Apache parallel database for semi-structured JSON data with SQL++, LSM storage and spatial/text indexes. Couchbase Server: Memory-first distributed JSON database with SQL++, search, vector indexes and mobile sync.

key differences

  • Licensing: AsterixDB is open source (permissive) (Apache License 2.0); Couchbase Server is source-available (Business Source License 1.1 (source); commercial Enterprise Edition).
  • Transactions: AsterixDB offers limited ACID; Couchbase Server offers full.
  • Only AsterixDB has streaming ingest.
  • Only Couchbase Server has transactions, vector search, change data capture, triggers, ttl / expiry.

choose asterixdb for

  • +Analytics over large semi-structured JSON datasets
  • +Spatial and text queries over social media or sensor feeds
  • +Database systems research and teaching (SQL++, LSM, parallel execution)
  • +Querying data lakes on HDFS or object storage alongside managed data

choose couchbase for

  • +User profiles and session stores at high concurrency
  • +Travel, retail and gaming backends with strict latency SLAs
  • +Offline-first mobile and edge apps with Couchbase Lite
  • +Caching layer that also persists and can be queried
