TL;DR

Cassaforte is a Clojure client for Apache Cassandra. It is built around CQL 3 and focuses on ease of use. You will likely find that using Cassandra from Clojure has never been so easy.

2.0.0-rc2 is a release candidate for 2.0.

Changes between 2.0.0-rc1 and 2.0.0-rc2

Fixes Race Condition in Async Operations

Async database operations no longer suffer from a race condition between issueing them and definiting callbacks on the returned future value.

Compression Option

:compression is a new option that can be used when connecting:

(require '[clojurewerkz.cassaforte.client :as client])

(let [s (client/connect ["127.0.0.1"] "my-keyspace" {:compression :snappy})]
  )

Valid compression values are:

  • :snappy
  • :lz4
  • :none (or nil)
