Getting a mapping

After having set our mappings for processing types, we sometimes need to control or analyze the mapping to prevent issues. The action to get the mapping for a type helps us to understand the structure or its evolution due to some merge and explicit type guessing.

Getting ready

You need a working ElasticSearch cluster and the mapping created in the previous recipe.

How to do it...

The HTTP method to get a mapping is GET.

The URL formats for getting mapping are as follows:

http://<server>/_mapping
http://<server>/<index_name>/_mapping
http://<server>/<index_name>/<type_name>/_mapping

For getting a mapping from in an index, we need to perform the following steps:

1. If we consider the type order of the previous chapter, the call will be as follows:

   curl -XGET 'http://localhost:9200/myindex/order/_mapping?pretty=true'
   

2. The result returned by ElasticSearch should be as follows:

   {
       "order": {
           "properties": {
               "customer_id": {
     ...
