How to update existing data from kafka indexing service?

we have druid cluster, and ingest data by kafka indexing service.

there are some dock at druid website, but . but they are not for kafka inexing service way

May i know if there is any way to update the existing data ?



Did you mean doing a re-state of your data since your current/older segments now need to reflect latest information? If that’s the case, then you can re-ingest the data with a given interval along with the latest information but you have to delete first the segments that maps to that same interval you are updating.

Hi Fanlong,

I was recently able to do this by firing off an indexing task of type IngestSegmentFirehose, with transformSpec set to whatever you want to update.
