Shortest KIP discussion ever :) Here are my notes. Feel free to correct or expand:
SSL: Harsh is rebasing after Kafka-1928, and resolving an issue with support for specific API KIP-4 - ISR in Metadata request: We prefer to preserve this information. KIP-25 - System Tests: Geoffrey posted an update with discussion summary, there were no objections to the proposal. We will wait a day before starting a vote. New consumer - Separate the API changes for metadata to a new JIRA. Since the new consumer is still work in progress, there's no need for KIP for every modification.
