| maxEventBatchSize| 10| The maximum number of events included in a batch for a single invocation. Must be at least 1.|
152-
| minEventBatchSize<sup>1</sup>| 1| The minimum number of events desired in a batch. The minimum applies only when the function is receiving multiple events and must be less than `maxEventBatchSize`.<br/><br/>**NOTE:** The minimum size is not a strict guarantee. A partial batch is dispatched if a full batch cannot be prepared before the `maxWaitTime` has elapsed. Partial batches are also likely for the first invocation of the function after scaling takes place.|

| maxWaitTime<sup>1</sup>| 00:01:00| The maximum interval that the trigger should wait to fill a batch before invoking the function. The wait time is only considered when `minEventBatchSize` is larger than 1 and is otherwise ignored. If less than `minEventBatchSize` events were available before the wait time elapses, the function is invoked with a partial batch. The longest allowed wait time is 10 minutes.<br/><br/>**NOTE:** This interval is not a strict guarantee for the exact timing on which the function is invoked. There is a small magin of error due to timer precision. When scaling takes place, the first invocation with a partial batch may occur more quickly or may take up to twice the configured wait time.|
154154
| batchCheckpointFrequency| 1| The number of batches to process before creating a checkpoint for the event hub.|
155155
| prefetchCount| 300| The number of events that is eagerly requested from Event Hubs and held in a local cache to allow reads to avoid waiting on a network operation|
