Size Category of Database Tables

The size category determines the size of the initial memory reserved for the table on the database. Values between 0 and 9 can be specified. A number of expected rows from the table are assigned to these values.

Size Category Expected Rows
0 0 to 1,000
1 1,000 to 4,200
2 4,200 to 17,000
3 17,000 to 68,000
4 68,000 to 270,000
5 270,000 to 540,000
6 540,000 to 1,000,000
7 1,000,000 to 2,100,000
8 2,100,000 to 4,300,000
9 4,300,000 to 170,000,000

If the initial space reserved is exceeded, a new memory area is added implicitly in accordance with the chosen size category.

Other versions: 7.31 | 7.40 | 7.54
