I’m trying make Filtered DimensionSpecs using druid java API same as explained http://druid.io/docs/latest/querying/dimensionspecs.html#filtered-dimensionspecs.
These are only valid for multi-value dimensions. If you have a row in druid that has a multi-value dimension with values [“v1”, “v2”, “v3”] and you send a groupBy/topN query grouping by that dimension with query filter for value “v1”. In the response you will get 3 rows containing “v1”, “v2” and “v3”. This behavior might be unintuitive for some use cases.
I need only v1 row.
But I can’t find any examples of how using it.
Any clue appreciate.
