• Migration Plan
  • We will have a two staged migration plan
  • Stage 1:
    • message.format.version=0.10.1-1
    • The broker should understand the attribute flag as well as Null for the value for log compaction
    • If consuming client is of older version, we down convert the message if attribute flag is set, nulling the value so that they preserve existing behaviour
  • Stage 2 (once all consumers and producers are updated / new installs):
    • set message.format.version=0.10.2 and rolling restart brokers
    • The broker only understands the attribute flag for log compaction
