Hi all,
Thanks in advance for the help!
I want to rename a field in an index 'everywhere'. By everywhere, I mean that I don't want my graphs and dashboard based on this field to be impacted, I don't know if there is any possibility to do it.
I found this like on the web : https://stackoverflow.com/questions/43120430/elasticsearch-mapping-rename-existing-field
It's using an Ingest pipeline, a Rename processor and the Reindex API but I don't want to create a new index because I have more than hundred graphs included in many dashboards (means : very long to update everything with the new name of my field)
Thanks again for your help !
Regards
Guillaume
[EDIT] - quick edit just to say that i'm running elasticsearch 6.4.3 and also to say why do I want to rename a field. For the moment I have something like :
- logs before 10th Dec I have into them myOldFieldName = user1
- logs after 10th Dec I have into them myNewFieldName = user1
and I'd like the same myNewFieldName = user1 for all my logs
