Hello! I have a potential situation where I will have a lot of sensor data coming in very often. (every second or so) The sensor data is from physics type measurements, and will normally follow a slowly changing pattern with sinusoidal disturbances. The overall shape of the data is more important than catching high frequency disturbances.
I had the idea of taking the Fourier transform of the waveform and storing the waveform internally that way to reduce storage requirements. When I get some free cycles, I may try doing this. I would want it to be done in the database in such a way that the user can still join to a table using this internal storage scheme. Why am I mailing this list? I'd like to ask if anyone has heard of someone doing anything like this. I did a small search of the lists and internet but didn't come up with anything. I just don't want to re-invent the wheel.
