I am using an Event Hub Trigger function written in javascript/nodejs. When message producer writes thousands of messages to the event hub the function receives between 2-4 messages at a time. Below is the host.json file for the function app. Is there anyway to achieve larger batch sizes?

{
    "eventHub": {
        "maxBatchSize": 64,
        "prefetchCount": 256,
        "batchCheckpointFrequency": 1
    }
}

根据我们的文档64是默认的批处理大小.

According to our documentation 64 is the default batch size.
