| <p>The Apache Gora team are pleased to announce the immediate availability of |
| Apache Gora 0.6.</p> |
| <p>This release addresses a modest <a href="http://s.apache.org/gora-0.6">47 issues</a> with some being |

| <h3 id="8-january-2015-gora-upgrades-to-hadoop-25x-and-hbase-098x">8 January, 2015: Gora upgrades to Hadoop 2.5.X and HBase 0.98.X<a class="headerlink" href="#8-january-2015-gora-upgrades-to-hadoop-25x-and-hbase-098x" title="Permalink">¶</a></h3> |
| <p>Today our Jira issue <a href="https://issues.apache.org/jira/browse/GORA-375">GORA-375</a> was resolved |
| with the result that the Gora community can now upgrade their systems to operate on Hadoop 2.X |
| and HBase 0.98. |
| Specifically the versions which we recommend are as follows:</p> |
| <ul> |
| <li>Apache Hadoop 2.5.2</li> |
| <li>Apache HBase 0.98.8-hadoop2</li> |
| </ul> |
| <p>Best efforts have also been made to retain backwards compatibility for Hadoop 1.X users, |
| therefore we have upgraded to, and still support Hadoop 1.2.1 via the addition of our |
| Shim layers. For further details on our Shim layers and pluggable Hadoop support please |
| see Jira issue <a href="https://issues.apache.org/jira/browse/GORA-375">GORA-346</a>. Additional |
| documentation for the use of Shim layers within Gora will soon be documented and linked to |
| from our <a href="http://gora.apache.org/current/index.html#gora-modules">current documentation</a>.</p> |

| Apache Gora 0.5.</p> |
| <p>This release addresses no fewer than <a href="http://s.apache.org/0.5report">44 issues</a> with many being |
| improvements and new functionality. Most notably the release includes the |
| addition of a new module for MongoDB, Shim ffunctionality to support |
| multiple Hadoop versions, improved authentication for Accumulo, better |
| documentation for many modules, and pluggable solrj implementations |
| supporting a default value of http for HttpSolrServer. Available options |
| include http (HttpSolrServer), cloud (CloudSolrServer), concurrent |
| (ConcurrentUpdateSolrServer) and loadbalance (LBHttpSolrServer).</p> |
| <p>Suggested Gora database support is as follows</p> |

| <p>We recently heard some excellent news that Gora is now implemented as a |
| <a href="https://fisheye6.atlassian.com/browse/camel-git/components/camel-gora">Camel Component</a> within Camel trunk.</p> |
| <p>Apache Camel is a rule-based routing and mediation engine which provides a Java object based implementation of |
| the Enterprise Integration Patterns using an API (or declarative Java Domain Specific Language) to configure |
| routing and mediation rules. The domain specific language means that Apache Camel can support type-safe |
| smart completion of routing rules in your IDE using regular Java code without huge amounts of XML configuration |
| files; though XML configuration inside Spring is also supported.</p> |
| <p>You can use this module with the following Maven configuration</p> |
| <pre><code><dependency> |
| <groupId>org.apache.camel</groupId> |
| <artifactId>camel-gora</artifactId> |
| <version>x.x.x</version> |
| <!-- use the same version as your Camel core version --> |
| </dependency> |
| </code></pre> |
| <p>You can find more information on the history of the development on the relevant <a href="https://issues.apache.org/jira/browse/CAMEL-4817">Jira ticket</a>.</p> |

| <p>The Apache Gora team are proud to announce the release of Gora 0.4. |
| This release addresses no fewer than 60 issues. 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. |
| A full list of changes in this release can be seen in |

| <p>After a successful <a href="http://www.google-melange.com/gsoc/homepage/google/gsoc2013">Google Summer of Code 2013</a> |
| project, Gora has been adopted as a core persistence abstraction for the popular graph processing |
| library in use at companies such as Facebook, Twitter, Linkedin and many more.</p> |
| <p>The integration of these two awesome Apache projects has as main motivation the |
| possibility of turning Gora-supported-NoSQL data stores into Giraph-processable graphs, |
| and to provide Giraph the ability to store its results into different data stores, |
| letting users focus on the processing itself. For more information please see the |

| <p>The biggest event within Apache Gora's history was revealed on 24/01/2012 when it was announced that Apache Gora |
| was to be established as a Top Level Project entity within the Apache Software Foundation. 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. |

| <h3 id="15-january-2012-apache-gora-announces-full-support-for-hector-client">15 January, 2012: Apache Gora announces full support for <a href="ext:hector"><b>Hector Client</b>:</a><a class="headerlink" href="#15-january-2012-apache-gora-announces-full-support-for-hector-client" title="Permalink">¶</a></h3> |
| <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: |
| <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> |
| 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. |
