Encoding graph data in SQL
I’ve been doing research and I found a great database for my purposes online. Each record has a number of interesting parameters, but I’m completely confused by the voltage_curve
which stores a binary blob. I found a record where I know what the curve roughly looks like, it goes up to a few volts and slowly ramps down. The problem is that I have no idea how to decode the data! I had a look around the internet and the initial byte sequence seems to point me to LZ4 compression, but that yielded no results – I get told that the data is invalid. How can this curve be encoded? I’m considering the possibility that only the y-values are encoded in equal time periods. Or maybe only the subsequent differences are stores? Any ideas?
