> Project Information
> ---------------------
> BeamSQL has a long list of of aggregation/aggregation analytics functionalities to support. 
> To begin with, you will need to support this syntax:
> {code:sql}
> analytic_function_name ( [ argument_list ] )
>   OVER (
>     [ PARTITION BY partition_expression_list ]
>     [ ORDER BY expression [{ ASC | DESC }] [, ...] ]
>     [ window_frame_clause ]
>   )
> {code}
> As there is a long list of analytics functions, a good start point is support rank() first.
> This will requires touch core components of BeamSQL:
> 1. SQL parser to support the syntax above.
> 2. SQL core to implement physical relational operator.
> 3. Distributed algorithms to implement a list of functions in a distributed manner. 
> 4. Enable in ZetaSQL dialect.
> To understand what SQL analytics functionality is, you could check this great explanation doc: https://cloud.google.com/bigquery/docs/reference/standard-sql/analytic-function-concepts.
> To know about Beam's programming model, check: https://beam.apache.org/documentation/programming-guide/#overview
