Binary Release vs Data Push

  • binary release needs to go through compilation and tests, which may take a few hours in a CI/CD system
  • data push is relatively small, mostly configurations, should be rolled out quickly(in minutes instead of hours). This is useful for controlled feature roll out(by feature flag, and sampling percentage) or operational changes(like whitelist/blacklist). Data push should be a separate system that can quickly changes things in prod without changing code and binary.
