Exporting and Importing Data with GemFire XD
You can use system procedures, gfxd commands, or Apache DdlUtils to import and export data into GemFire XD from other databases.
gfxd commands provide a convenient method for exporting, modifying, and importing database schemas and data using SQL scripts or XML-formatted files. However, for larger data sets (over several gigabytes of data) consider using the stored procedures instead for better performance. See Using GFXD Commands to Export and Import Data.
The gfxd commands are based on Apache DdlUtils, and if you are proficient with DdlUtils you can optionally use DdlUtils with Apache Ant to import and export data. See Using Apache DdlUtils to Import Data.
