maxBatchSize

The maximum number of events to include in a single batch delivered to the target. The service delivers up to this many events per batch; fewer may be delivered when the batch window elapses or the target's per-batch limit is smaller. This is a maximum, not a guaranteed count. Valid range is 1-500 (default: 10, or the target API's per-batch maximum). The resolved value applied by the service is returned on read.
