CREATE INDEX statementUse the CREATE INDEX statement to create an index for one or more columns in a table, or on values returned by a UDR that uses column values as arguments.
FILLFACTOR OptionUse the FILLFACTOR option to specify the degree of index-page fullness when you want to create compacted indexes or provide information for the expansion of an index at a later date.
Providing a Low Percentage Value

Providing a Low Percentage Value

If you provide a low percentage value, such as 50, you allow room for growth in your index. The nodes of the index initially fill to a certain percentage and contain space for inserts. The amount of available space depends on the number of keys in each page as well as the percentage value.

For example, with a 50-percent FILLFACTOR value, the page would be half full and could accommodate doubling in size. A low percentage value can result in faster inserts and can be used for indexes that you expect to grow.
