Apache Spark reassigned SPARK-12203:
------------------------------------
Assignee: Apache Spark
> Add KafkaDirectInputDStream that directly pulls messages from Kafka Brokers
> using receivers
> -------------------------------------------------------------------------------------------
>
> Key: SPARK-12203
> URL: https://issues.apache.org/jira/browse/SPARK-12203
> Project: Spark
> Issue Type: New Feature
> Components: Streaming
> Reporter: Liang-Chi Hsieh
> Assignee: Apache Spark
>
> Currently, we have DirectKafkaInputDStream, which directly pulls messages
> from Kafka Brokers without any receivers, and KafkaInputDStream, which pulls
> messages from a Kafka Broker using receiver with zookeeper.
> As we observed, because DirectKafkaInputDStream retrieves messages from Kafka
> after each batch finishes, it posts a latency compared with KafkaInputDStream
> that continues to pull messages during each batch window.
> So we try to add KafkaDirectInputDStream that directly pulls messages from
> Kafka Brokers as DirectKafkaInputDStream, but it uses receivers as
> KafkaInputDStream and pulls messages during each batch window.
