Is it necessary to use Kafka?

[radicaled42]

I'm reviewing the implication of installing Sentry and I would like to know if possible to replace Kafka for RabbitMQ/SQS?
As far as I understand Sentry use Rabbit/Redis to cache project configs and counts events and keeps track of quotas.
While Kafka is used to manage alert trigger and postprocess-event

Is this correct?
Would it be possible to modify the chart to use RabbitMQ or SQS to replace Kafka?

Thanks
