average
Parameters
value
How many (column family, column qualifier) combinations are present per row in the table, averaged over all rows in the table. e.g. A table with 2 rows: * A row with cells in "family:col" and "other:col" (2 distinct columns) * A row with cells in "family:col", "family:other_col", and "other:data" (3 distinct columns) would report (2 + 3)/2 = 2.5 in this field.
