Hi team,
1. How can one create mappings for numbers such that large numbers are represented as K (for 1000), M(Million) etc?
2. How does one create custom mappings? (Such as bit rate: bps, or other ways of representation)
I have a feeling this needs to be done at ES. Any examples? Can this be done after the index is created?
Thanks in advance

1. Can be done with field formatters - [https://www.elastic.co/guide/en/kibana/current/managing-fields.html](https://www.elastic.co/guide/en/kibana/current/managing-fields.html)
2. Maybe with the same thing, depends what you want to do really.
You could do it in ES as well, but you'd need to reindex existing data.

Perfect!! This helped a lot. Also, I used the 'docs' link in the mapping section of Kibana to understand what all can be achieved.
Thanks @warkolm
