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}




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. Build benchmarks to measure performance of your implementation.



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.
