Elasticsearch Delete Mapping Property
You can not do that. Just forget that this value exists... ;-)If you really need to remove it, you will have to reindex your documents.
You can use the new _reindex api for this, you could even PUT a new _mapping to the dest index before running the reindex so you can change the properties of the fields in your index.
To do a reindex and removing a property, you can do this:
POST /_reindex{ "source": { "index": "twitter" }, "dest": { "index": "new_twitter", }, "script": { "inline": "ctx._source.remove('whatever')" }}if you would use this in combination with the _aliases API you can modify indexes without having any 'downtime'
It's not currently possible to remove a property from a mapping. In order to remove all values of a property from all records, you need to reindex all records with this property removed.
