Can not have enough instances

Closed this issue · 2 comments

Hi Team,

We have around 100 event hubs partitions and are using a Premium Function plan, however, the maximum instance we can get is only 15 which is affecting the performance.

Is there any configuration within [azure-functions-eventhubs-extension] we can make to use more instances?

We are migrating from Sevice Bus for the costing reason while the performance on Service bus is much better.

Extension in use: 5.0.0-beta.6

host.json:
{
"version": "2.0",
"aggregator": {
"batchSize": 1000,
"flushTimeout": "00:00:05"
},
"healthMonitor": {
"enabled": true,
"healthCheckInterval": "00:00:10",
"healthCheckWindow": "00:02:00",
"healthCheckThreshold": 6,
"counterThreshold": 0.8
},
"extensions": {
"eventHubs": {
"eventProcessorOptions": {
"maxBatchSize": 128,
"prefetchCount": 512
},
"initialOffsetOptions": {
"type": "fromEnqueuedTime",
"enqueuedTimeUtc": "2022-05-25T18:00:00Z"
}
}
}
}

Many thanks!

@HaochenQ, can you please privately share you function app name and a timestamp when you have "the maximum instance we can get is only 15 which is affecting the performance"
