Description

Hi there,

Now that geo_point is one of the native elasticsearch types (as far as I can tell), it seems as though logstash should have a filter for this data type out of the box.

Yes, I am aware that we can manually map these types, but that's an extra step that logstash is already handling gracefully for all of the other types.

I've noticed that the Twitter input plugin maps correctly to geo_points so it should be possible in a filter as well. There are geo_point fields in the geoip section of properties in the default "logstash-*" template as well.

There is an existing issue opened about such a feature (https://github.com/elastic/logstash/issues/3291) but no one has replied to it.

Is there something holding this development back?

Thanks for the help! James

Research direction
Examine existing Logstash filter plugins for patterns, especially the geoip filter in the default template. Review the Twitter input plugin that correctly maps geo points. Look at the linked issue #3291 for prior discussion. The filter should add a mapping similar to how other types are handled automatically.
