How to set elasticsearch index.mapping.total_fields.limit to unlimited

Question

I am dealing with a huge json blob so I need to open the seal. How can I set elasticsearch index.mapping.total_fields.limit to unlimited?

Answer 1

You cannot set it to unlimited. In fact, it has been intentionally limited to prevent mapping explosion. You can read the the github issue here.

The only to achieve what you want is by using a high value.

You can specify that value when creating the index:

PUT test
{
  "shopfront": {
    "index.mapping.total_fields.limit": 2000,
    "number_of_shards": 5,
    "number_of_replicas": 2
  },
  "mappings": {
    ...
  }
}

Or if it is for an existing index:

PUT shopfront/_settings
{
  "index.mapping.total_fields.limit": 2000
}
