we have some raw data with one field wrong from April. But we cannot reload data from the source. Is there any way that we can modify only one field? for example:
_time id name value:
20210406 1 "SMT" 60 to be 20210406 1 "Node" 60
20210416 100 "SMT" 80 to be 20210416 100 "Node" 80
Ingested data is immutable. There is no way to change, modify, or edit data once it's in a Splunk index.
The best you can do is add logic to your queries to replace "SMT" with "Node" in the name field. Once the April data expires you can remove that logic.
Thanks. But the issue not all of "SMT" in April was wrong. Only part of them need to be update. Anyway, thanks for your reply.
