Brian Hulette updated BEAM-8560:
--------------------------------
    Description: 
`BigQueryIO.write` should be able to validate the schema of the input 
PCollection against the schema for this table (either retrieved from 
DataCatalog, or from BQ metadata). Then we can fail at pipeline construction 
time rather than waiting until execution.

At the very least this should work when writing Beam Rows.
