There was a problem hiding this comment.
the problem is b/c in some agg literals it allows stringify parameter type with ; as the separator. this conflicts with my usage of ; which indicates the "next literal hint".
Thus i used another 3-character splitter ;:; to indicate hint-literal boundaries.

add all supported agg functions to follow up with #11034
the following can be added very soon (some complication due to testing)
distinctCountBitmapis not yet supported, can be added later*TupleSketchfunctions not yet supportedSTUnionagg function*MVvariance of agg functions will be added in [multistage] Support multi-value aggregation functions #11216the following functions require some revisit
histogramnot yet supported due to complex ARRAY constructor_version of the stats function such asCOVAR_POPis not supported, (where ascoVarPopis) due to calctie built-in operator table conflict.argmin/argmaxis not supported due to conflicting signature (e.g. arg column at 1st vs arg column at last convention differs between pinot and calcite)funnelCountdue to its complex syntax, there should be an easier solution in v2
