averageColumnsPerRow property
How many column qualifiers are present in this column family, averaged over all rows in the table.
e.g. For column family "family" in a table with 3 rows: * A row with cells in "family:col" and "other:col" (1 column in "family") * A row with cells in "family:col", "family:other_col", and "other:data" (2 columns in "family") * A row with cells in "other:col" (0 columns in "family", "family" not present) would report (1 + 2 + 0)/3 = 1.5 in this field.
