userinputnode properties
The User Input node provides an easy way to create synthetic data—either from
scratch or by altering existing data. This is useful, for example, when you want to create a test
dataset for modeling.
Example
node = stream.create("userinput", "My node")
node.setPropertyValue("names", ["test1", "test2"])
node.setKeyedPropertyValue("data", "test1", "2, 4, 8")
node.setKeyedPropertyValue("custom_storage", "test1", "Integer")
node.setPropertyValue("data_mode", "Ordered")

If Combined is specified, records are generated for each combination of set
values and min/max values. The number of records generated is equal to the product of the number of
values in each field. If Ordered is specified, one value is taken from each column
for each record in order to generate a row of data. The number of records generated is equal to the
largest number values associated with a field. Any fields with fewer data values will be padded with
null values. |
