The EDB Postgres Data Adapter for Hadoop® allows read access from EDB Postgres Advanced Server and PostgreSQL to Hadoop Hive. EDB Postgres connects to a mapping table in Hive to access data stored in HDFS (Hadoop Distributed File System). Predicate pushdown for SELECT and WHERE improves the result set returned via the network. The Adapter is Hortonworks Yarn certified, and certified to run on Apache Spark using the Spark Thrift Server.
