select * from NEW org.apache.derby.diag.SpaceTable('SYS','SYSTABLES') AS x;using it for my table, the estimated size of a record is coming to be 131 bytes. The table consists of 5 bigints, 3 smallints, 1 timestamp and a varchar. The avg length of the varchar is 14chars. So, total size of the record size should have been 5*8+3*2+14+(bytes for timestamp)+any additional per field/record data all put together shouldn't be more than 70/80 bytes. So, why am I getting 131 bytes?
