What do you mean by "PCollection of dicts, each having different key
values"? What's the type of the PCollections? I assume that you want to
merge two PCollections of KV such as
PCollection[("a", 1), ("b", 2), ("c", 3)] + PCollection[("a", 4), ("d", 5),
("e", 6)]. Is that correct?On Tue, Feb 11, 2020 at 9:19 AM Douglas Martins <[email protected]> wrote: > Hi, > > I am developing a Pipeline thats reads from and writes to BigQuery.
