Optionals cause 1 bool + size of orignal type. Due to alignment needs, this can balloon to 8 bytes for 64-bit integers. Making an optional 8 byte integer take 16 bytes.

sara.williamson@mongodb.com I think that would be helpful if the Tiger team already has ideas on what the specific goals are (specifically around what performance goals and non-goals should we be basing the success of this work on), and if there is any missing context beyond the the description in this ticket. |

The recommendation is to make this into a project to better identify the requirements/implementation. cc: phoebe.du@mongodb.com |
