 The batch output node (influx batch) sends a list of *points* together in a batch to InfluxDB in a slightly different format from the output node, more in line with the underlying node.js [influx library version 5.x](https://www.npmjs.com/package/influx). In each point you must specify the measurement name to write into as well as a list of tag and field values. Optionally, you can specify the time to tag that point at, defaulting to the current time.
