URL: http://GPUDB_IP_ADDRESS:GPUDB_PORT/filter/bylist
Calculates which records from a table have values in the given list for the corresponding column. The operation is synchronous meaning that GPUdb will not return a response until all the objects are fully available. The response payload provides the count of the resulting set. A new resultant set (view) which satisfies the input filter specification is also created if a input parameter view_name is passed in as part of the request.
For example, if a type definition has the columns 'x' and 'y', then a filter by list query with the column map {"x":["10.1", "2.3"], "y":["0.0", "-31.5", "42.0"]} will return the count of all data points whose x and y values match one of the values in the respective x- and y-lists. If the filter_mode option is set to 'not_in_list' then the filter will match all items that are not in the provided list(s).
