Is there a graphic tool to display (and maybe change) elasticsearch mappings?

Question

I am using https://github.com/mobz/elasticsearch-head, which is awesome (!), but it does not have that functionality.

After putting several mapping into the index, I'd like to be able to view them graphically. Is that possible?

Answer 1

You can make new indexes, with new mappings. I've used this to translate logstash mappings from one type to another. I have used this reindex plugin to much success. It makes the streaming one index into another much simpler and takes essentially only 2 http requests.

Something like this:

$ curl -XPOST http://elnode:9200/<New Index Name> -d @<new mapping>.json
$ curl -XPUT  http://elnode:9200/<New Index Name>/logs/_reindex\?searchIndex=<Old Index Name>\&searchType=logs

Now you have a new index of new mapping with old index's data. You could then delete the old and make an alias with the old index's name that points to the new.

A bit of work, but I'd needed it for keeping old logstash data in a new format.
