Resolution: Duplicate
Closing this one, since W/ SAMZA-775, we should be able to configure the consumer buffer to avoid this problem.

> Key: SAMZA-772
> URL: https://issues.apache.org/jira/browse/SAMZA-772
> Project: Samza
> Issue Type: Bug
> Components: kafka
> Affects Versions: 0.9.1
> Reporter: Nick Lee
> Assignee: Yi Pan (Data Infrastructure)
>
> The default setting for systems.system-name.samza.fetch.threshold will pre-fetch 50,000 messages from Kafka, ignoring the availability of heap space. When working with relatively large messages, this can lead to Samza job failures.
> A simple solution would be to restrict the maximum size of org.apache.samza.system.SystemConsumers.unprocessedMessagesBySSP.table to no more than a configurable percentage (35% by default?) of the maximum heap space.
