> *Background*
> Messages produced by Hooks have potential to be larger than 1MB, which is the size threshold imposed by Kafka.
> Although, compressing the messages (see [ATLAS-2064|https://issues.apache.org/jira/browse/ATLAS-2064]) alleviates the the problem, it is not a complete solution. It is possible even for compressed messages to exceed the size threshold.
> *Solution*
> If the compressed message produced exceeds the size threshold, split the messages. Accumulate the message at consumer end. 
> Account for cases such as:
> - Messages are not received in order they are produced.
> - Atlas server is shutdown before it can consume all the split messages.
