A new #Jepsen report! We analyzed @redpandadata (a Kafka-compatible distributed queue) and discuss crashes, aborted reads, inconsistent offsets, and lost/stale messages, along with some potentially surprising aspects of the Kafka transaction protocol. https://jepsen.io/analyses/redpanda-21.10.1
Redpanda has addressed most of these issues in the just-released 21.11.15, and the upcoming 22.1.1 fixes aborted reads and lost writes with transactions--lost/stale messages are still under investigation. A few more issues require only documentation to address.
