When a request is made to add JSON object to a particular index and if that index does not exist, then this API automatically creates that index and also the underlying mapping for that particular JSON object. This functionality can be disabled by changing the values of following parameters to false, which are present in elasticsearch.yml file. action.auto_create_index:false index.mapper.dynamic:false You can also restrict the auto creation of index, where only index name with specific patterns are allowed by changing the value of the following parameter − action.auto_create_index:+acc*,-bank* Note − Here + indicates allowed and – indicates not allowed.
