@ijuma > Thanks for the PR. A high-level question, what are we trying to optimize for here? >Requests that don't include topic ids Requests that include topic ids Both Some kind of balance of both where we compromise a bit to keep the code maintainable The goal of this PR is to gracefully handle the new topic case. Currently in kafka, when we create a new topic, the leader and Isr request is sent first, then the update metadata request. This means that we will often encounter transient "unknown_topic_id" errors. In the new world of topic IDs, we will see this as "unknown topic ID" errors. The current logic returns a top level error and delays all partitions. This is a regression from previous behavior, and so this PR's goal is to return to the behavior where we store the unknown partition in the session until it can be resolved.
