Overview of the GemFire-Greenplum Connector

The GemFire-Greenplum Connector facilitates the mirroring of the entries of an entire Pivotal GemFire® region into a Pivotal Greenplum Database® (GPDB) table. The connector also facilitates the mirroring of the entries of an entire GPDB table into a GemFire region.

All transfers are initiated from and specified within GemFire. Data copied from GemFire to GPDB makes use of the GemFire export functionality. Data copied from GPDB to GemFire makes use of the GemFire import functionality. The specification of mappings of tables within GPDB to regions in GemFire may be set up with gfsh commands or specified within a GemFire cache.xml file. Further mappings identify which GemFire fields are to be imported from or exported to GPDB table columns. A subset of the fields and columns may be specified, and then only that subset are imported or exported.
