Apache Druid

I guess my question here would be, Am I missing something around how to set the Indexer runtime?

And, my runtime:
```        druid.service=druid/indexer
        druid.worker.capacity=10
        druid.processing.numThreads=10
        druid.indexer.task.baseTaskDir=/druid/data/baseTaskDir
        druid.server.http.numThreads=10```


are you setting this? `druid.indexer.runner.javaOptsArray`

<https://druid.apache.org/docs/latest/configuration/index.html#middlemanager-configuration>

I’m not using the middle manager. I’m using the Indexer process

<https://druid.apache.org/docs/latest/configuration/index.html#indexer>

are you conforming to this
```The amount of direct memory needed by Druid is at least druid.processing.buffer.sizeBytes * (druid.processing.numMergeBuffers + druid.processing.numThreads + 1). You can ensure at least this amount of direct memory is available by providing -XX:MaxDirectMemorySize=&lt;VALUE&gt; at the command line.```

Always need to go back to the basics :smile:

So, that wasn't the issue.Also, my setting were correct.
```druid.processing.numThreads=10
druid.processing.buffer.sizeBytes=536870912
druid.processing.numMergeBuffers=5```
That's 8GB, and my setting is 24G.
Yet, still getting `java.lang.OutOfMemoryError: Direct buffer memory`
