We are getting exception while storing data more than 32K in an index field. We just need to store the data without any indexing.
Elasticsearch version: 6.0.0
Field Data Type: "type": "keyword" and "index": false
[2018-01-21T19:51:07,956][DEBUG][o.e.a.b.TransportShardBulkAction] [fwall_feeds_data] failed to execute bulk item (update) BulkShardRequest [[fwall_feeds_data]] containing  requests java.lang.IllegalArgumentException: DocValuesField "nlp_data" is too large, must be <= 32766
Please suggest how can we resolve this issue.
