Druid data transformation

Hi All,

I have one more question with respect to the following requirement.

We have data coming from our logs which have say few common dimension values and few different dimension values

along with the metrics. e.g. One row in our log may translate to multiple events in Druid.

So I wanted to know whether Druid spec provides some hook for Data Transformation while doing real time ingestion.



This functionality has been added to druid-api but is not in master yet:

You can use javascript to transform your events. This will be slower than using a stream processor I think.
