      We added a block meta structure to each page in disaggregated storage which should have an impact on the performance. The current improvement proposal is to make the block meta in page as a pointer, in dissag storage it is a pointer to the structure where in attached storage it is just null, so we only pay 8 bytes for the null pointer in attached storage mode.

      This ticket is to investigate that and proceed with this approach if we decide to do so.
