There was a problem hiding this comment.
we already have the field properties in PIP-404. And maybe we can also use the field to store bookieClusterName

Motivation
Pulsar brokers are statically bound to a single Bookie cluster via
bookkeeperMetadataServiceUriat startup. When the underlying Bookie clusterhits capacity limits or non-recoverable failures, there is no runtime way to
re-target brokers to another Bookie cluster without restart and full data
migration. This PIP introduces zero-downtime Bookie cluster switching by
attributing each ledger to its owning cluster and routing reads accordingly.
