What is Couchbase?

Couchbase is a distributed and highly scalable memory-first document database that provides the capabilities you like most from a traditional relational database. Plus, it’s fast, flexible, always on, and has no single point of failure. (Note: Couchbase is not CouchDB)

Key attributes of Couchbase include:

  • Data stored as JSON
  • Data queried via SQL++
  • Supports multi-document ACID transactions
  • Uses key-value access
  • Has a built-in search engine
  • Provides high-performance caching
  • Automatically shards data
  • Supports analytic workloads
  • Has an advanced mobile database

“Couchbase is a go-to database for innovators. It’s a modern, yet very mature, solution that’s been used for years in retail, e-commerce, travel, hospitality, healthcare, media, and many other industries…”
