Welcome to the Apache Gora project!

The Apache Gora open source framework provides an in-memory data model and persistence for big data. Gora supports persisting to column stores, key value stores, document stores and RDBMSs, and analyzing the data with extensive Apache Hadoop™ MapReduce support. Gora uses the Apache Software License v2.0. Gora graduated from the Apache Incubator in January 2012 to become a top-level Apache project.

15 January, 2012: Apache Gora announces full support for Hector Client:

Some time ago, the Apache Gora development team made the decision to support Hector as the primary Apache Cassandra client. This decision enables Gora to build on the expressiveness offered by the Hector API, some features include:

  • high level, simple object oriented interface to Cassandra.
  • failover behavior on the client side.
  • connection pooling for improved performance and scalability.
  • JMX counters for monitoring and management.
  • configurable and extensible load balancing (round robin (the default), least active, and a phi-accrural style response time detector).
  • complete encapsulation of the underlying Thrift API and structs.
  • automatic retry of downed hosts.
  • automatic discovery of additional hosts in the cluster.
  • suspension of hosts for a short period of time after several timeouts.
  • simple ORM layer that works.
  • a type-safe approach to dealing with Apache Cassandra's data model.
  • As an Apache community we value community over code, this move is definitely a step in the right direction towards bringing together two diverse communities, whilst during process undoubtedly making both Apache Gora and Hector better technologies. Here at Gora we look forward to working with the Hector community.
