[raveeram-db]

Feature request

Which Delta project/connector is this regarding?

• Spark
• Standalone
• Flink
• Kernel
• Other (fill in here)

Overview

This feature request is to build a Connector for Flink (specifically Flink 2.0) using the Java Delta Kernel (which is purpose-built to enable Connector development while abstracting away Delta protocol details) instead of the existing, deprecated Delta Standalone based Flink Connector.

Motivation

The current Flink connector is built on Delta Standalone, which is no longer under active development as noted in the Delta 3.1.0 release notes. Delta Kernel is the forward-looking foundation for connectors, with support for features like Deletion Vectors, Column Mapping, IcebergCompatV1/V2 etc. A Flink connector built on the Kernel would unlock access to these features and better align with the long-term direction of the Delta project.
