> 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.
