Project Overview

PostgresForest is designed for the use of Business Intelligence apps and (read intensive) Web apps.

  • PostgreSQL JDBC driver derivative: PostgresForest is a modified JDBC driver to enable clustering features.
  • High Availability: PostgresForest enables to implement an high-available database system with its replication facilities.
  • Parallel Query Processing: PostgresForest can understand and execute parallel queries in a shared-nothing distributed database.
  • On-Line Recoverying: PostgresForest can recover a node from its failure condition without the service downtime.
