* Consider ways of storing rows more compactly on disk
- o Store disk pages with no alignment/padding?
o Reorder physical storage order to reduce padding?
+
+ This involves having the user-specified order of columns
+ be different from the physical order. SELECT * would
+ need to reorder the physical values to match the
+ user-specified ordering.
+
+ o Store disk pages with no alignment/padding?
+
+ This necessitates adding CPU-required padding when moving
+ rows from disk to memory.
+
o Support a smaller header for short variable-length fields?
