Rui Wang updated BEAM-9198:
---------------------------
Description:
BeamSQL has a long list of of aggregation/aggregation analytics functionalities
to support.
To begin with, you will need to support this syntax:
analytic_function_name ( [ argument_list ] )
OVER (
[ PARTITION BY partition_expression_list ]
[ ORDER BY expression [{ ASC | DESC }] [, ...] ]
[ window_frame_clause ]
)
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.
