Look up - 0.10.1

Hi
I am able to do look up for particular dimension with below extranction function

“dimensions”:[{“type”:“extraction”,“dimension”:“id_ho_g”,“outputName”:“id_h_g”,“extractionFn”:{“type”:“registeredLookup”,“lookup”:“keyvaluecache”}}]

But any one explain me how can i handle if I require all column. I mean if I required all dimensions , and if I have particular key in any dimension that should be lookup from lookup cache.

Thanks

You might want to check Lookup Introspection - https://druid.apache.org/docs/latest/querying/lookups.html. See “Introspect A Lookup” section.
