So for example, if you were to execute a rebalance, with the below command,
it would move partitions at no more than 50MB/s.
<pre class="language-bash">$ bin/kafka-reassign-partitions.sh
--bootstrap-server localhost:9092 --execute --reassignment-json-file
bigger-cluster.json --throttle 50000000</code></pre>
When you execute this script you will see the throttle engage:
- <pre class="line-numbers"><code class="language-bash"> The throttle limit
was set to 50000000 B/s
- Successfully started reassignment of partitions.</code></pre>
+ <pre class="line-numbers"><code class="language-bash"> The inter-broker
throttle limit was set to 50000000 B/s
+ Successfully started partition reassignment for foo1-0.</code></pre>
<p>Should you wish to alter the throttle, during a rebalance, say to
increase the throughput so it completes quicker, you can do this by re-running
the execute command passing the same reassignment-json-file:</p>
- <pre class="language-bash">$ bin/kafka-reassign-partitions.sh
--bootstrap-server localhost:9092 --execute --reassignment-json-file
bigger-cluster.json --throttle 700000000
- There is an existing assignment running.
- The throttle limit was set to 700000000 B/s</code></pre>
+ <pre class="language-bash">$ bin/kafka-reassign-partitions.sh
--bootstrap-server localhost:9092 --execute --reassignment-json-file
bigger-cluster.json --additional --throttle 700000000
+ The inter-broker throttle limit was set to 700000000 B/s</code></pre>
Review comment:
We should add `--additional` argument in the script to change the
throttle value.
