Subject [jira] [Commented] (FLINK-4722) Consumer group concept not working properly with FlinkKafkaConsumer09
Date Mon, 03 Oct 2016 16:20:20 GMT

    [ https://issues.apache.org/jira/browse/FLINK-4722?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15542774#comment-15542774

Sudhanshu Sekhar Lenka commented on FLINK-4722:
-----------------------------------------------

Thnx for your reply.

Is there any configuration or logic available to modify  KafkaConsumer#subscribe() for specific
partitions ?

if i have   one topic which  has 3 partitions(0,1,2).   and 3 FlinkKafkaConsumer09  is it
possible to  subscribe particular partitions.
as inside FlinkKafkaConsumer09 it subscribe to all partitions by default ?
that cause problem of getting duplicate data and filter it again inside flink which causing
performance issue for us.

> When Kafka one Topic has 3 partition and 3 FlinkKafkaConsumer09 connected to that same
topic using "group.id" ,"myGroup" property . Still flink consumer get all data which are push
to each 3   partition . While it work properly with normal java consumer. each consumer get
specific data.
