Enabling High Availability and Data Consistency Features

The fault tolerance and the high-availability features of Greenplum Database can be configured.

Important: When data loss is not acceptable for a Greenplum Database cluster, Greenplum master and segment mirroring is recommended. If mirroring is not enabled then Greenplum stores only one copy of the data, so the underlying storage media provides the only guarantee for data availability and correctness in the event of a hardware failure.

For information about the utilities that are used to enable high availability, see the Greenplum Database Utility Guide.
