Fernando Morales updated BEAM-1330:
-----------------------------------
Description:
DatastoreIO writes batches upto 500 entities (rpc limit for Cloud Datastore),
before flushing them out. The writes are non-transactional and thus do not
support duplicate keys in the writes. This can be problem, especially when
using a non global windowing, where multiple windows for the same key end up in
the same batch, and prevents the writes from succeeding.
