------------------------------------
Summary: Automate replica lag tuning
Key: KAFKA-1546
URL: https://issues.apache.org/jira/browse/KAFKA-1546
Project: Kafka
Issue Type: Improvement
Components: replication
Affects Versions: 0.8.1.1, 0.8.0, 0.8.1
Reporter: Neha Narkhede
Currently, there is no good way to tune the replica lag configs to
automatically account for high and low volume topics on the same cluster.
For the low-volume topic it will take a very long time to detect a lagging
replica, and for the high-volume topic it will have false-positives.
One approach to making this easier would be to have the configuration
be something like replica.lag.max.ms and translate this into a number
of messages dynamically based on the throughput of the partition.
