Adjacent space, but can't help but wonder why Confluent did so much better than MapR

https://news.ycombinator.com/item?id=20053188 and https://www.computerweekly.com/news/252468013/MapR-collapse-... have some context on MapR's demise.

IMO they were simultaneously worse situated for near-real-time stream processing and for S3-esque cloud storage, areas Kafka and Confluent excelled.
