9aman opened a new issue, #2849:
URL: https://github.com/apache/helix/issues/2849
**Context**
This is about the use of Helix in **Apache Pinot**. I want to infer the
**queue size** of the **executor service** that handles **state transitions**.
```
2024/05/09 03:46:55.385 INFO [HelixTaskExecutor]
[ZkClient-EventThread-137-pinot-zookeeper-headless:2181] Submit task:
755de162-49a1-4092-8e11-945c8e5e7674 to pool:
java.util.concurrent.ThreadPoolExecutor@18623363[Running, pool size = 40,
active threads = 40, queued tasks = 160, completed tasks = 33065]
```
Above are the logs emitted by Helix. These logs contain the details of the
executor service used for the state transition messages.
On analysis of the code, I found that the following line in the
**HelixTaskExecutor** class provides the above details:
`LOG.info("Submit task: " + taskId + " to pool: " + exeSvc);`
**Is your feature request related to a problem? Please describe.**
I wanted to access the helix task executor queue size. The `_executorMap`
inside HelixTaskExecutor cannot be accessed. This limits our access to the
executor service.
Is there a way to get the queue size?
**Describe the solution you'd like**
Ability to fetch the queue size of the executor service that handles state
transition requests inside HelixTaskExecutor.
