Per [the last thread above](https://github.com/apache/beam/pull/6461#discussion_r219555610), a next step may be to remove `READ` and `CREATE_VIEW` as primitives, after which we could get rid of this logic / greatly simplify things. My instinct is to clarify that bigger picture, and then make runners/SDKs, their tests, and some independent tests all conform to it, rather than enshrine this accidental/transitional state in tests at this time, but definitely interested in discussion there. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
