Doc values are not enabled by default

(Jonathan Spooner) #1

The deep dive on doc values article says that

"Doc values are enabled by default for all fields except analyzed strings"

However, when looking at the field data usage I'm seeing fields that are set to "not_analyzed" consuming field data memory.

GET /_stats/fielddata?fields=*
"gh9": {
    "memory_size_in_bytes": 601821608

My template

"gh9": {
     "index": "not_analyzed",
     "type": "string"

Our Elasticsearch version is 2.4.1.

Do you know why it appears that this non_analyzed string is consuming field_data memory?
