It is important to note one key aspect before proceeding. In Spark Runner, PCollectionView inherently utilizes Broadcast variables. As a result, it is not considered a checkpoint target.

Checks are failing. Will not request review until checks are succeeding. If you'd like to override that behavior, comment assign set of reviewers

There are something flaky tests. I'll fix it.

The existing test testStreamingSideInputAsSingletonView will be removed due to its flaky nature. (The output of GenerateSequence is inconsistent depending on the Test Spark Runner runtime environment.) This test will be replaced with ViewTest.testWindowedSideInputNotPresent.
