[jira] [Updated] (KAFKA-7558) Dependency on __consumer_offsets at connection time

     [ https://issues.apache.org/jira/browse/KAFKA-7558?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alex Rykov updated KAFKA-7558:
------------------------------
    Description: It looks like currently(in version 2.0.0) consumer's ability to receive messages depends on availability of  certain __consumer_offsets partitions(I assume corresponding to group id). It seems reasonable for consumers that rely on Kafka to maintain offset, but unnecessary for the ones that maintain that offset independently. Would be good for consumer to either have an ability to opt out or to check __consumer_offsets partitions availability on commit.  (was: It looks like currently(in version 2.0.0) there is no way to indicate for the consumer that it is going to maintain offset independently. As a result if I understand it correctly specific partitions of  __consumer_offsets need to be available. If __consumer_offsets is used only to maintain offsets then this dependency is not required when consumer chooses to manage offset independently.)
        Summary: Dependency on __consumer_offsets at connection time  (was: Ability for consumer to indicate no intention to commit)
