1. dont producers now have much higher latency since they have to wait for writes to s3.

2. if the '5-10x cheaper' is mostly due to cross AZ savings, isnt that offered by AWS MSK offering too?

1. Yeah, we mention at the end of the post the P99 produce latency is ~400ms. 2. MSK still charges you for networking to produce into the cluster and consumer out of it if follower fetch is not properly configured. Also, you still have to more or less manage a Kafka cluster (hot spotting, partition rebalancing, etc). In practice we think WarpStream will be much cheaper to use than MSK for almost all use-cases, and significantly easier to manage.

How does the cost compare if follower fetch is properly configured?

1. what payload size and flush interval is that latency measured against?
