Set Minimum Version

Delete catalog versions to manage storage costs and enable lifecycle management of versioned layers. Catalog version deletion does not impact any other layer types stored in a catalog, only versioned layers. Catalog version deletion safely removes data from versioned layers only and in a way that doesn't break dependencies which exist between different versioned layers in a single catalog. Before deleting versions, consider reviewing the usage information for the versions to make sure no processes, such as pipelines, are depending on the deleted versions. If you delete a catalog version that is being used by a process like a pipeline, you will break the process. For information on viewing the usage information, see the Logs, Monitoring and Alerts User Guide.

To delete versions, use the PublishApi provided by the data-client module. The only required parameter is the HRN of the catalog:

val publishApi = DataClient().publishApi(catalogHrn)
publishApi.setMinimumVersion(minimumVersion = 2)

// create publishApi for a catalog
PublishApi publishApi = DataClient.get(myActorSystem).publishApi(catalogHrn);
publishApi.setMinimumVersion(5L);
