How to update a record in druid

Hi All,

By mistake one record got loading wrong in druid,I want to update the count of the record in druid.

Please suggest how to update the one record in druid.

Iam using segment granularity as Day.

Thanks in advance.

Hi,

It’s not possible to update a single row in Druid like RDBMS. You can correct the actual raw data and re-ingest again in druid, after the re-ingestion the new segments will be used for query and old ones will be unloaded by historicals.

Please go through the below link which talks on updating the existing data in druid:

https://druid.apache.org/docs/latest/ingestion/data-management.html#update

Thanks and Regards,
