How to rebuild the data using indexing service?

Hi,

I have a data source with a dozen of dimensions, but recently I
decided that I want to stop sending a particular dimension. My
question is, how can I entirely rebuild Druid segments, from
2017-01-01 to 2017-03-01 - on a hourly basis - so that I delete
all historical data related to that dimension once and forever?

Hi,
does http://druid.io/docs/latest/ingestion/update-existing-data.html help ?
