For a columnar database, that's a continuous chunk of memory. Assuming 32bit q defaults to 32bit int, 1.1 billion integers across four machines means each 64-core (with 4 threads/core) KNL chip is averaging over 275M elements of int array, or 1.1M 32bit int operations per thread. Now think again whether that's amazing or not.
- shaklee3 10y agoYou're not accounting for the memory bandwidth at all. Yes, that's still amazing. Try doing that in opentsdb.
