Kafka AlterShareGroupOffsets Response Wire Format v0 — Binary Protocol Layout

What is AlterShareGroupOffsets?

Resets or advances a share group's start offset for specific partitions, the equivalent of kafka-consumer-groups.sh --reset-offsets for share groups. Use this to skip over poison-pill records causing repeated delivery failures across all members.
