this is probably going to have very weird results for the age use case e.g. this will say that age "100" is smaller than age "20" . I believe, you would need to at least support a flag saying whether the comparison should be done by converting string to numbers.

@himanshug / @b-slim how would you feel if the numeric condition just used the comparator from io.druid.query.topn.AlphaNumericTopNMetricSpec ?

@drcrallen

and possibly make it "alphaNumeric" instead of just numeric?

Is it possible to test each of the return cases for isAlphaNumeric both true and false?

@b-slim would it make sense to add less than and greater than filters as well while we're at it?
Between could be expressed as a combination of those or have it's own implementation, depending on whether it's worth to optimize, but it seems a bit strange to have between but not < <= > >=

b-slim commented Nov 11, 2015

@xvrl i see how this can be useful, but i think we can have between, < <= > and >= all together.
i do prefer to have between since it saves the amount of bytes sent and and deserialized.
so i guess we can start with this, then i will send another PR of the rest of the troops.

@xvrl did you mean adding more filters or updating the api for same filter?
@b-slim @xvrl can we handle all cases by calling it a "bound" filter and based on whether user specified one or both of "lower" and "upper", the filter should be able to do appropriate thing.
so if user specifies
"lower" only : then it becomes a lower bound filter
"upper" only: then it becomes a upper bound filter
"lower" and "upper" both: then it becomes between filter

I think another PR introduced a separate variable for 0xFF in this context, can you use that?
