> Very exciting! Thank you for leading the way here, Uwe. > >> The most horrible thing I have seen is that our CFS file format starts the "inner" files totally unaligned. We should fix the CFSWriter to start new files always at multiples of 8 bytes. I will open an issue about this. > > I ran into this just yesterday as I was playing around with aligning vectors in their index files to see if any perf bump could be gained (the header seems to be 50 bytes usually, so some padding is needed). And then when I asserted alignment, realized that CFS was messing with it. In fact for CFS file we don't even need to change the file format / version number. We just have to make sure that CFS writer starts new inner files aligned to 8 bytes. That should be easy to implement. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
