---------------------------
Summary: BeamSQL aggregation analytics functionality (was: BeamSQL
aggregation analytics functions )
> BeamSQL aggregation analytics functionality
> --------------------------------------------
>
> Key: BEAM-9198
> URL: https://issues.apache.org/jira/browse/BEAM-9198
> Project: Beam
> Issue Type: Task
> Components: dsl-sql
> Reporter: Rui Wang
> Priority: Major
> Labels: gsoc, gsoc2020, mentor
>
> 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.
