Persisting Table Data to Hadoop
GemFire XD provides the capability to store partitioned table data in a Hadoop Distributed File System (HDFS). Using HDFS as a persistent store enables you to capture high rates of table updates in HDFS for later processing in Hadoop. Or, you can choose to manage very large tables in GemFire XD--tables much larger than can be managed in memory, even when overflowing to GemFire XD disk stores.
If you are currently using GemFire XD 1.3.x with Pivotal HD for HDFS table support, continue to use your installed version of the product. Pivotal will provide maintenance releases for version 1.3.x until GemFire XD 1.4 is certified with an upcoming version of Pivotal HD.
