Hi David,
I've read through your post in #elasticsearch and have been trying to reproduce your scenario. Unfortunately I'm not having much success. Here's what I'm observing; maybe you can tell me what you are observing that's different:
I installed the mapper-size plugin in Elasticsearch 2.2.0 and creating an index with the following mapping:
PUT foo
{
"mappings": {
"bar": {
"_size": {
"enabled": true
}
}
}
}
Then I indexed a couple of documents into it, of varying sizes.
When I create an index pattern for this index in Kibana, I do not see the _size field in the list displayed by Kibana:
Given that, I cannot use the _size field in any visualizations for performing aggregations on it.
