Compresses an enterprise geodatabase by removing states not referenced by a version and redundant rows.


  • To improve geodatabase performance, the geodatabase should be compressed periodically. A compressed geodatabase is more efficient. A geodatabase that is never compressed is more likely to develop errors.

  • Once a geodatabase is compressed, deleted records cannot be recovered.

  • Compression of geodatabases not only reduces space requirements but can also reduce overall retrieval times.

  • When the Compress tool is executed, the geodatabase is unavailable until compression is completed.

  • Only the geodatabase administrator can perform compression.

ParameterExplanationData Type

Specify the database connection file that connects to the enterprise geodatabase to be compressed. Connect as the geodatabase administrator.
