The Resource attribute is used to specify the computation cost of a user defined
|
||
function (UDF). IsStateful asserts that the function is stateful; IsExpensive
|
||
asserts that the function is expensive to compute. The information is useful in
|
||
generating better execution plan. For example, expensive associative aggregation
|
||
functions enables the use of multiple aggregation layers.
