Dear node-red Experts, I have a node that sends multiple output @ 5 ms speed. After that node is the influxDB output node where it write data into influxDB. But here's the issue, I am having a trouble because it seems influxDB cannot accomodate the speed of (5ms) to write data on its database. U…

[image] Henjoe: Note, that the payload should be buffed, or in a form of array or anything , I just need it to buff to a certain amount or time Can you explain what you mean by that? I think there may be a couple of typos there. For influxdb you could use the influx batch node which takes a…

Thanks for replying Colin, Currently I am using the influx out (not the batch), and I actually want to change my influx out to influx batch out node. I think you actually get what I want to do. As we know there is an format for batch node right? I already used join node in other applications. Can …

What does the incoming data look like? Feed it into a debug node and do a screenshot if possible.

Thank Colin, Will get back to you regarding the screenshot of debug node ( I am not on my testing environment right now) . But to give you an idea the data is something like this: msg.payload = { value: value, timestamp: 12839801982093, quality: Good } it is somet…

Are all the records for the same measurement and field (ie 'value')? What about the quality, is that a field or a tag?

Yes all measurements have the same fields. And they are all fields, I don't have Tags on my measurements. Thanks Colin! I appreciate your effort in here.

Ok, in that case all you need to do is to get the data into an array in msg.payload, something like [ {measurement: "whatever the measurement name is", fields: {value: 73, quality: "good"}, timestamp: 1283....}, {measurement: "whatever the measurement name is", fields: {value: -1, quality: "bad"}, …

Thanks Colin! Yeah I should make quality as Tag, thanks for giving me this idea :slight_smile: You're such an awesome guy! Anyways.. So the formatting will be done thru a function node right? Because the join node doesnt format like that? Am I right in here?

You could do it in a function node, or a bit of clever JSONata in a Change node I expect, but I don't get on with JSONata. In a Function node you can do it using msg.payload.map(). map() is a function that you call on an array and it applies a function to each member of the array and gives you bac…

Hello Colin, Thanks for this idea. I will try this. And I hope I get a good response on my influxDB. I'll get back in this forum the results on this so if anyone has the same issue I get encountered might have reference too. Again, thank you very much. With kind regards,
