Couple of examples can think of off the top of my head from recording logs for analysis. 1. It might be better to buffer up logs, then sort on a different column than time. You may benefit from the delta encoding or prefix encoding. 2. If you have tracking info, which is usually a random like a UUID or something, then ditch it. Not debugging with this dataset so don’t waste the space on a crazy high noise column. Shit like that.
