KAFKA-4115: grow default heap size for connect-distributed.sh to 1G
----
> 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.
