John Roesler updated KAFKA-8902:
--------------------------------
Fix Version/s: 2.4.0
> Benchmark cooperative vs eager rebalancing
> ------------------------------------------
>
> Key: KAFKA-8902
> URL: https://issues.apache.org/jira/browse/KAFKA-8902
> Project: Kafka
> Issue Type: Sub-task
> Components: streams
> Reporter: Sophie Blee-Goldman
> Assignee: John Roesler
> Priority: Major
> Fix For: 2.4.0
>
>
> Cause rebalance and measure:
> * overall throughput
> * paused time
> * (also look at the metrics from
> (https://issues.apache.org/jira/browse/KAFKA-8609)):
> ** accumulated rebalance time
> Cluster/topic sizing:
> ** 10 instances
> ** 100 tasks (each instance gets 10 tasks)
> ** 1000 stores (each task gets 10 stores)
> * standbys = [0 and 1]
> Rolling bounce:
> * with and without state loss
> * shorter and faster than session timeout (shorter in particular should be
> interesting)
> Expand (from 9 to 10)
> Contract (from 10 to 9)
> With and without saturation:
> EOS:
> * with and without
> Topology:
> * stateful
> * windowed agg
> Key Parameterizations:
> 1. control: no rebalances
> 2. rolling without state loss faster than session timeout
> 3. expand 9 to 10
> 4. contract 10 to 9
