[GitHub] [beam] jhnmora000 opened a new pull request #11845: [BEAM-9198] BeamSQL aggregation analytics functionality
jhnmora000 opened a new pull request #11845:
URL: https://github.com/apache/beam/pull/11845
A simple Analytic Functions experiment for BeamSQL created
in order to understand the query processing workflow of
BeamSQL and Calcite.
The experiment is implemented in the test BeamAnalyticFunctionsExperimentTest.testSimpleOverFunction(),
when executing it a "BEAM_LOGICAL but does not implement
the required interface" exception is thrown.

Review comment:
Now your code will hit this line, which will crash.
You can try to create BeamWindowRel now in convert function.
