762 762 The amount of payload stored under this category. Payload is the data 763 763 part of table entries and the key part of index entries. The percentage 764 764 at the right is the bytes of payload divided by the bytes of storage 765 765 consumed. 766 766 767 767 Bytes of metadata 768 768 769 - The amount of formatting and structural information stored on for the 769 + The amount of formatting and structural information stored in the 770 770 table or index. Metadata includes the btree page header, the cell pointer 771 771 array, the size field for each cell, the left child pointer or non-leaf 772 772 cells, the overflow pointers for overflow cells, and the rowid value for 773 - rowid table cells. In other words, metadata is everything that is not 774 - unused space and that is not content. 773 + rowid table cells. In other words, metadata is everything that is neither 774 + unused space nor content. The record header in the payload is counted as 775 + content, not metadata. 775 776 776 777 Average payload per entry 777 778 778 779 The average amount of payload on each entry. This is just the bytes of 779 780 payload divided by the number of entries. 780 781 781 782 Average unused bytes per entry
