fujian updated KAFKA-19858:
---------------------------
Issue Type: Bug (was: Improvement)
> Add configurable min.insync.replicas (default=2) for __remote_log_metadata
> topic
> --------------------------------------------------------------------------------
>
> Key: KAFKA-19858
> URL: https://issues.apache.org/jira/browse/KAFKA-19858
> Project: Kafka
> Issue Type: Bug
> Components: Tiered-Storage
> Reporter: fujian
> Assignee: fujian
> Priority: Minor
>
> The __remote_log_metadata internal topic currently lacks a configurable
> min.insync.replicas setting, relying on the broker-level default (typically
> 1). This creates a data loss risk in production environments, as writes may
> be acknowledged by only a single replica.
> This is inconsistent with __transaction_state, which explicitly sets
> min.insync.replicas=2 via the transaction.state.log.min.isr broker
> configuration. Both topics store critical metadata and should have equivalent
> durability guarantees.
