+ Note: The cooperative rebalancing protocol has been the default since 2.4, but we have continued to support the
+ eager rebalancing protocol to provide users an upgrade path. This support will be dropped in a future release,
+ so any users still on the eager protocol should prepare to finish upgrading their applications to the cooperative protocol in version 3.1.
+ This only affects users who are still on a version older than 2.4, and users who have upgraded already but have not yet
+ removed the upgrade.from
config that they set when upgrading from a version below 2.4.
+ Users fitting into the latter case will simply need to unset this config when upgrading beyond 3.1,
+ while users in the former case will need to follow a slightly different upgrade path if they attempt to upgrade from 2.3 or below to a version above 3.1.
+ Those applications will need to go through a bridge release, by first upgrading to a version between 2.4 - 3.1 and setting the upgrade.from
config,
+ then removing that config and upgrading to the final version above 3.1. See KAFKA-8575
+ for more details.
