Announcing the release of AgensGraph 2.5

<p><span style="font-weight: 400;">The AgensGraph Development Team are pleased to announce the release of AgensGraph v2.5.</span></p>
<p>AgensGraph is a new generation multi-model graph database for the modern complex data environment. AgensGraph is a multi-model database, which supports the relational and graph data model at the same time that enables developers to integrate the legacy relational data model and the flexible graph data model in one database. AgensGraph supports ANSI-SQL and openCypher (<a href="http://www.opencypher.org/" rel="nofollow">http://www.opencypher.org</a>). SQL queries and Cypher queries can be integrated into a single query in AgensGraph.</p>
<p>AgensGraph is based on the powerful PostgreSQL RDBMS, and is very robust, fully-featured and ready for enterprise use. AgensGraph is optimized for handling complex connected graph data and provides plenty of powerful database features essential to the enterprise database environment including ACID transactions, multi-version concurrency control, stored procedure, triggers, constraints, sophisticated monitoring and a flexible data model (JSON). Moreover, AgensGraph leverages the rich eco-systems of PostgreSQL and can be extended with many outstanding external modules, like PostGIS.</p>

<h2><strong>Major Improvements in AgensGraph v2.5.</strong></h2>
<p>&nbsp;</p>
<h3><strong>1. Performance</strong></h3>
<p><span style="font-weight: 400;">Partitioning, a unique feature of relational DB, can now be used in AgensGraph as well.&nbsp;</span></p>
<p>&nbsp;</p>
<p><span style="font-weight: 400;">1.1. Large-scale data processing</span></p>
<p><span style="font-weight: 400;">&ndash; With partitioning, large-scale data processing is improved</span></p>
<p><span style="font-weight: 400;">&ndash; Improved performance speed and the convenience of data management</span></p>
<p><span style="font-weight: 400;">&ndash; Hybrid query (Cypher+SQL) performance has been improved in relation to large data processing performance.&nbsp;</span></p>
<p>&nbsp;</p>
<p><span style="font-weight: 400;">1.2. Query Performance</span></p>
<p><span style="font-weight: 400;">&ndash; When querying and aggregating large amounts of data, the performance of the query has been improved by hash join using parallel processing&nbsp;&nbsp;</span></p>
<p>&nbsp;</p>
<h3><strong>2. Ease of Use</strong></h3>
<p><span style="font-weight: 400;">A stored procedure has been added. The stored procedure can package and store multiple queries into one logic.&nbsp;</span></p>
<p>&nbsp;</p>
<p><span style="font-weight: 400;">2.1. Convenience of Data Management</span></p>
<p><span style="font-weight: 400;">&ndash; The newly added stored procedure eliminates repetitive tasks, thus saving time&nbsp;</span></p>
<p><span style="font-weight: 400;">&ndash; Convenience of expansion and maintenance has significantly improved</span></p>
<p>&nbsp;</p>
<h3><strong>3. Algorithms</strong></h3>
<p><span style="font-weight: 400;">New graph algorithms are provided in a package.&nbsp;</span></p>
<p>&nbsp;</p>
<p><span style="font-weight: 400;">3.1. Latest Graph Algorithms</span></p>
<p><span style="font-weight: 400;">&ndash; A total of 7 advanced graph algorithms such as centrality, community detection, and similarity, etc are the core of graph analysis and shall be included in the package.&nbsp;</span></p>
<p>&nbsp;</p>
<h3><strong>4. High Availability</strong></h3>
<p><span style="font-weight: 400;">Information systems with high availability can operate normally for a long period of time without failure.</span></p>
<p>&nbsp;</p>
<p><span style="font-weight: 400;">4.1. Agpool&rsquo;s High Availability</span></p>
<p><span style="font-weight: 400;">Updated Agpool to improve high availability&nbsp;</span></p>
<p><span style="font-weight: 400;">&ndash; Load Balancing: when multiple users execute a query at the same time, the query is distributed across multiple servers for processing&nbsp;</span></p>
<p><span style="font-weight: 400;">&ndash; Auto Failover: when the master server fails, the slave server takes over instead&nbsp;</span></p>
<p>&nbsp;</p>
<p><span style="font-weight: 400;">The new version is immediately available for </span><a href="https://bitnine.net/agensgraph-downloads/"><span style="font-weight: 400;">download</span></a><span style="font-weight: 400;">.</span></p>
