KIP-1170 — Unify cluster metadata bootstrapping
Accepted Kafka 4.4 KRaft
Merges the KRaft quorum bootstrap checkpoint (00000000000000000000-0000000000.checkpoint) and the cluster metadata bootstrap checkpoint into a single unified bootstrap.checkpoint file. Having two separate bootstrap checkpoints for overlapping concerns (KRaft quorum state vs. cluster metadata state) creates maintenance complexity and divergence risk during cluster initialization.
