KIP-1233 — Maximum lengths for resource names and IDs

Discussion AdminBroker

Proposes enforcing maximum length limits on Kafka resource names and identifiers (topic names, consumer group IDs, transactional IDs, client IDs, etc.). Without length limits, extremely long identifiers can inflate group coordinator data structures, cause unreadable CLI output, degrade broker performance, or be exploited for denial-of-service attacks.
