I have a system where data arrives in waves. There are a potentially large number of sensors that report data every few minutes.
My node-red flow grabs this data and writes it to influxdb. I'm using a delay node as a rate limiter to even out the spikes.
It's working fine at the moment.
However, I was wondering about the details of how Delay works.
Specifically, how and where does Delay store the delayed data. Is it in memory, on the disk, or ?
I'm asking because I'm running this on a Raspberry Pi 4, and I'd like to understand what might break the system as the number of sensors increases.
All feedback welcome.
