 sampling01

 

In addition to this property, it is possible to apply a SQL filter on each table to add a restriction to the source table.

The «SQL Order By» property allows to apply a sort on the read of the source table, as the tool will take the first «Row percentage» records.

Stambia Sampling tool usage

The principle of the «Stambia Sampling» tool is to specify a sampling percentage on some tables and propagate the sampling on the other tables with the primary & foreign keys, as shown in the following data physical model:
