| The time in ms that a topic partition leader will wait before expiring producer ids. Producer IDs will not expire while a transaction associated to them is still ongoing. Note that producer ids may expire sooner if the last write from the producer id is deleted due to the topic's retention settings.

The following configuration will also be modified:

NOTE: Setting producer.id.expiration.ms to be lower than the delivery timeout will increase the likelihood of duplicates. Any expiration of producer IDs means that the producer can no longer take advantage of idempotency guarantees.
This configuration will be dynamic.
Compatibility, Deprecation, and Migration Plan
...
Although this would be the most seamless transition for compatibility, it doesn't allow users to see benefits from the new configuration. The default of 1 day should not cause issues with typical clients, so it seems fair to set the default lower.
Make configuration static
Originally this configuration was created to be static. However, in the case of a misbehaving client, it may be necessary to take action to change the value. When the broker is overloading, rolling the cluster may be tricky. By having a dynamic config, we can reduce impact.
