• Returns a PTransform returning a PCollection with the same contents as the input PCollection, but with the given Row (aka Schema'd) Coder, based on an "example" element. E.g.

    const unknown_schema_pcoll = ...
    const schema_pcoll = unknown_schema_pcoll.apply(
    withRowCoder({int_field: 0, str_field: ""}));

    This is particularly useful for declaring the type of the PCollection to invoke cross-language transforms.

    Type Parameters

    • T extends Object


    • exemplar: T

    Returns PTransform<PCollection<T>, PCollection<T>>
