Description copied from class: FlinkKafkaConsumerBase

Creates the fetcher that connect to the Kafka brokers, pulls data, deserialized the data, and emits it into the data streams.

Overrides:

createFetcher in class FlinkKafkaConsumer<T>

Parameters:

sourceContext - The source context to emit data to.

assignedPartitionsWithInitialOffsets - The set of partitions that this subtask should handle, with their start offsets.

watermarkStrategy - Optional, a serialized WatermarkStrategy.

runtimeContext - The task's runtime context.

Returns:

The instantiated fetcher

Throws:

Exception - The method should forward exceptions
