Benchao Li commented on CALCITE-5245:
-------------------------------------
[~jiaxuan] I agree with Julian that we can introduce these BigQuery functions,
you can find dialect-specific functions in {{SqlLibraryOperators}}. After that,
we can solve this issue by rewriting in {{RelToSqlConverter}}, and configs
could be put into {{SqlDialect}}.
