I have quite a few indexes matching the pattern logstash-*
In them I have a keyword called 'bytes_read'.
It's type according to elasticsearch is string. This is due to an issue with our logstash configuration. I have corrected this configuration.
- Is it possible to add a field to all existing index called _bytes_read that's in integer form?
- Is this achievable via the reindexing API?
- Is there a better way?
