Release 1.1.1

Release Date: December 20, 2023

Resolved Issues

VMware Greenplum Connector for Apache NiFi 1.1.1 resolves these issues:

Resolves CVE-2022-42889 by ceasing shipment of Apache commons-text library.
Resolves CVE-2023-1428, CVE-2023-32731, and CVE-2023-32731 by updating gRPC libraries (and their transitive dependencies) to version 1.53.0.

Release 1.1.0

Release Date: September 9, 2022


When a column in the target Greenplum Database table has no matching field in an incoming NiFi record and the PutGreenplumRecord processor Unmatched Column Behavior configuration setting specifies either Ignore Unmatched Columns or Warn on Unmatched Columns, the VMware Greenplum Connector for Apache NiFi sends no column value for the record to GPSS. If the Greenplum table definition includes a default value for the column, Greenplum Database writes the tuple with the default column value; otherwise Greenplum writes the tuple with a NULL column value.

Resolved Issues

VMware Greenplum Connector for Apache NiFi 1.1.0 resolves these issues:

Resolves an issue where a default column value was not applied when a NiFi record had no matching field; see Changes above.

Release 1.0.1

Release Date: June 14, 2022


VMware Greenplum Connector for Apache NiFi version 1.0.1 adds support for Greenplum Streaming Server versions 1.6.1+.

Release 1.0.0

Release Date: December 16, 2020


The VMware Greenplum Connector for Apache NiFi 1.0.0 release supports inserting, merging, and updating record-oriented data in Greenplum Database. You can set up an Apache NiFi dataflow that sends Avro, CSV, Parquet, JSON, or XML data to the Connector PutGreenplumRecord processor to write to a Greenplum table.

Known Issues and Limitations

The VMware Greenplum Connector for Apache NiFi 1.0.x has these known issues and limitations:

  • Using the Connector with Greenplum Streaming Server versions prior to v1.7.1 when loading timestamp without timezone type data into Greenplum Database may expose a data type conversion issue. This issue is resolved in Greenplum Streaming Server version 1.7.1; be sure to use the VMware Greenplum Connector for Apache NiFi version 1.0.1+ should you encounter this scenario.
  • If you run the Connector against Greenplum Streaming Server version 1.4.x or older, you must specify "ReuseTables": false in the gpss.json server configuration file that you use to start the Greenplum Streaming Server.
  • The Connector does not support SSL-encrypted connections to the Greenplum Streaming Server.
  • A dataflow that you create that routes Avro data from the QueryDatabaseTableRecord processor to the PutGreenplumRecord processor must set the Use Avro Logical Types property to true to send date and time data in the format supported by the Connector.
  • Apache NiFi bug NIFI-7817 causes the built-in ParquetReader processor to fail when you use it with Apache NiFi version 1.12.
  • Decimal types may lose precision when you use the Connector with Apache NiFi versions 1.10 and 1.11.
