[jira] [Created] (KAFKA-4115) Grow default heap settings for distributed Connect from 256M to 1G

Shikhar Bhushan created KAFKA-4115:
--------------------------------------

             Summary: Grow default heap settings for distributed Connect from 256M to 1G
                 Key: KAFKA-4115
                 URL: https://issues.apache.org/jira/browse/KAFKA-4115
             Project: Kafka
          Issue Type: Improvement
          Components: KafkaConnect
            Reporter: Shikhar Bhushan
            Assignee: Shikhar Bhushan


Currently, both {{connect-standalone.sh}} and {{connect-distributed.sh}} start the Connect JVM with the default heap settings from {{kafka-run-class.sh}} of {{-Xmx256M}}.

At least for distributed connect, we should default to a much higher limit like 1G. While the 'correct' sizing is workload dependent, with a system where you can run arbitrary connector plugins which may perform buffering of data, we should provide for more headroom.
