I have a table --- create Table mytable ( Id text, cdate timestamp,
Tk text, Primary key (id, cdate) ) with clustering order by (cdate desc); One of the partition key has 2,099,414 rows; using the following formula: row_size = sum_of_all_columns_ size_within_row + partition_key_size row_size = 32bytes (string) + 8 + 32 == 72 bytes partition_size = row_ size_average * number_of_rows_in_this_partition partition_size = 72 * 2099414 = 147,615 KB Cassandra system log reports: 128,064,307 bytes for this key Can someone explain the gap? Did I make any wrong assumption in calculating the row size/pk size? C* version is 3.0.15 Thanks, Subroto
