Introduction

With this action, Steadybit can dynamically modify a broker configuration to change the value of the following configuration num.io.threads.

Details

Kafka restricts large changes to its current configuration. If the requested number of network threads falls outside the permissible range, the extension applies intermediate adjustments incrementally until the target value is achieved.

Use Cases

• Limit I/O threads to reduce the broker’s capacity to perform disk operations, potentially causing increased latency or request timeouts.

Parameters

Parameter	Description	Default
Duration	The duration of the attack.	60s
Number of IO Threads	The number of io threads per broker. The value is rollback to the previous one at the end.
