Major improvements within the release scope comprise a complete upgrade to Apache Avro 1.7.X and overhaul of the Gora persistency API (such improvements enable Gora to be used to map much more expressive and complicated data structures than previously available), upgrades to Apache HBase 0.94.13, Apache Cassandra 2.0.X and Apache Accumulo 1.5.X. Users can also benefit from using Gora + Solr for object-to-datastore mapping with the addition of the new Solr module which uses Solr 4.X.

This is excellent news for the Gora community and we are looking forward to tackling the benefits and challenges brought by our new Top Level status. </p> </div> </div> </div> <div class="accordion-item"> <h2 class="accordion-header" id="150112h"> <button aria-controls="150112c" aria-expanded="false" class="accordion-button collapsed fw-bold" data-bs-target="#150112c" data-bs-toggle="collapse" type="button"> 15 January, 2012: Apache Gora announces full support for <a href="ext:hector"><b>Hector Client</b>:</a> </button> </h2> <div aria-labelledby="150112h" class="accordion-collapse collapse" data-bs-parent="#goraReleaseAccordion" id="150112c"> <div class="accordion-body"> <p>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: <ul> <li>high level, simple object oriented interface to Cassandra.</li> <li>failover behavior on the client side.</li> <li>connection pooling for improved performance and scalability.</li> <li>JMX counters for monitoring and management.</li> <li>configurable and extensible load balancing (round robin (the default), least active, and a phi-accrural style response time detector).</li> <li>complete encapsulation of the underlying Thrift API and structs.</li> <li>automatic retry of downed hosts.</li> <li>automatic discovery of additional hosts in the cluster.</li> <li>suspension of hosts for a short period of time after several timeouts.</li> <li>simple ORM layer that works.</li> <li>a type-safe approach to dealing with Apache Cassandra's data model.</li> </ul> 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. </p> </div> </div> </div> <div class="accordion-item"> <h2 class="accordion-header" id="240911h"> <button aria-controls="240911c" aria-expanded="false" class="accordion-button collapsed fw-bold" data-bs-target="#240911c" data-bs-toggle="collapse" type="button"> 24 September, 2011: Apache Gora 0.1.1-incubating release </button> </h2> <div aria-labelledby="240911h" class="accordion-collapse collapse" data-bs-parent="#goraReleaseAccordion" id="240911c"> <div class="accordion-body"> <p>The Apache Gora project made its second incubating release.
