Aggregation Function

[Calvin Dani <ca...@gmail.com>]

Hi,

The DBIS Lab @ Santa Clara University is working on JSON schema inference.
This functionality can be called using "array_schema()" , this query is a
logical extension of "array_avg()" aggregation query.

Utilizing the template of array_avg() in the Built-in Function and Function
collection file the array_schema() was implemented. During self review, a
lot of defined aggregate functions for
example SerializableAvgAggregateFunction
and IntermediateAvgAggregateFunction are not being utilised during
array_schema() query. Is it due to different use cases or am I utilising it
incorrectly?

Are there any resources to understand the functionality of aggregate
functions in the implementation?


Thank you and Regards
