Enhancement request - IBM Cloud Pak for Data – Redshift Connector

Hi IBM team,

 Kindly find an enhancement request for - IBM Cloud Pak for Data – Redshift Connector

 Problem: Using IBM Cloud Pak for Data –Redshift Connector (with WRITE MODE=LAOD), empty source tables are not getting loaded to target AWS-Redshift . By default, AVRO files are getting generated, and these files are erroring out while loading into Redshift. With current Redshift Connector, there is no option to change the default file generation format to other formats such as Parquet. We tried to load an empty Parquet file to redshift, and it got loaded without any issues.

 Error message on system log tables on redshift: "Invalid AVRO file found. Unexpected end of AVRO file"

 Enhancement request: Enhancement request is to provide an option to choose desired file format in Redshift connector.

 AWS support response on this: The PFR (ticket) that is in place to enable ingestion of empty Avro tables into Redshift is relatively new (4 months) with very few customer requests for the feature. It is not likely that will be included and implemented in the roadmap anytime soon.

 We have initially raised IBM # CS4063902 for this. But based on suggestions from IBM team that we are working with, we are raising this enhancement request.

 Kindly let us know if you need any additional details.
