What is the SQS-based system you are migrating from?

I'm currently building a data processing system that is backed by S3 -> SQS based events, for persistent message passing.

We have a number of systems, some use SQS, some use Kinesis. Part of the draw of Pulsar is having one piece of tech that we can unify everything over and offer more baseline features, like infinite retention via storage offloading or Pulsar IO connectors that standardize common operations. We aren't really targeting one use case, instead, we looked for the system that offered a broad set of features that other developers in the company want and is operationally doable with just a few people.
