FILTER statements typically use logical comparators to find values that do, and do not, meet certain criteria. In this example, the
FILTER statement drops rows for which the condition is FALSE from the dataset.
This transformation retains the same schema in the output table as in the input.
FILTERstatements remove rows from a dataset, in contrast to the
filter()function which removes values from an array. See Map, Filter, and Reduce. Because the syntax for transformations is case insensitive, Tamr recommends writing statement names in all uppercase and function names in all lowercase as a best practice.
