KeyDB vs CQEngine: What are the differences?

Developers describe KeyDB as "Open source lighting fast key-value database with advanced features". KeyDB is a fully open source database that aims to make use of all hardware resources. KeyDB makes it possible to breach boundaries often dictated by price and complexity. On the other hand, CQEngine is detailed as "An in-memory DataBase". It is a NoSQL indexing and Query Engine, for retrieving objects matching SQL-like queries from Java collections, with ultra-low latency.

KeyDB and CQEngine can be primarily classified as "In-Memory Databases" tools.

Some of the features offered by KeyDB are:

  • Active Replication
  • FLASH storage support
  • direct backup to AWS S3

On the other hand, CQEngine provides the following key features:

  • Ultra-fast
  • Query engine
  • No SQL

KeyDB and CQEngine are both open source tools. KeyDB with 1.76K GitHub stars and 98 forks on GitHub appears to be more popular than CQEngine with 1.06K GitHub stars and 171 GitHub forks.
