Change Logs

Add consumer group id to kafka params based on the schema hash when KafkaAvroSchemaDeserializer is used to avoid kafka connector caching the KafkaConsumer causing issues with schema evolution.

Impact

Kafka connector will create a new Kafka consumer whenever there's a change in the schema instead of using cached kafka consumer.

Risk level (write none, low medium or high below)

NA
