export gpdb

Export a region to GPDB. Export is supported from partitioned GemFire regions only. Data cannot be exported from replicated regions.

Availability: Online. You must be connected in gfsh to a JMX Manager member to use this command.

Syntax:

export gpdb --region=regionpath --type=value [--remove-all-entries(=value)]
Name Description Default Value
‑‑region Required. Region from which data is to be exported. Prefix the region name with a slash character.  
‑‑type Required. Specification of the functionality implemented for the export operation.
  • UPSERT updates rows already present in the GPDB table, and it inserts rows where not already present.
  • INSERT_ALL does a GPDB insert operation for each entry in the GemFire region.
  • INSERT_MISSING does a GPDB insert operation for each GemFire region entry for which there is no corresponding GPDB row; no updates are done for existing GPDB rows.
  • UPDATE updates rows already present in the GPDB table.
‑‑remove-all-entries Optional boolean value that, when true, removes all GemFire entries present in the specified region when the export operation is initiated, once changes have been successfully committed to the GPDB table. All exported region entries are removed, independent of which rows are updated or inserted into the GPDB table. false
