Release 2.2.0 Changes

Pivotal Greenplum 2.2.0 is a minor release that includes these changes:

  • This release introduces the Greenplum Database PL/Container language extension for Kubernetes, which enables users to create and run PL/R user-defined functions (UDFs) securely, inside a Kubernetes pod. See Deploying PL/Container for Kubernetes.

Known Issues and Limitations for Kubernetes Deployments

  • VMware does not support deployments that have been modified by adding layers to the packaged Docker images, or deployments that reference images other than the Greenplum Operator. VMware does not support changing the contents of the deployed containers and pods in any way.
  • Greenplum Database connector functionality is not supported. This includes Greenplum Streaming Server (gpss) and its API, Greenplum-Informatica Connector, Greenplum-Spark Connector, and the Greenplum-Kafka Integration.
  • Pivotal Greenplum for Kubernetes does not currently support cluster monitoring with Greenplum Command Center, the gpperfmon database, or related utilities. Use system-level monitoring tools such as Prometheus and Grafana until Greenplum Command Center support is available.
  • Pivotal Greenplum for Kubernetes does not support the built-in SNMP features that are available in Pivotal Greenplum Database.
  • Pivotal Greenplum for Kubernetes does not support installing Greenplum extensions that use the .gppkg format (and gppkg utility). Future releases will include these extensions as part of the distribution, as with MADlib.
  • The Greenplum Operator does not yet support changing all attribute values of a deployed Greenplum cluster. See Greenplum Operator Manifest File for details.
