What is the difference between mapping types and index per document type?

In API Gateway 10.3 version or lower, each document is stored in a single index and assigned a single mapping type. So, there will be only one gateway_default index with multiple mapping types like APIs, applications, analytics, etc.

In API Gateway 10.5 version onwards, mapping types have been removed and replaced with index per document type. Instead of storing APIs and analytics in a single gateway_default index, APIs are stored in the gateway_default_apis index and analytics in the gateway_default_analytics index.

For more information about the removal of mapping types and index per document type, please refer to Removal of mapping types | Elasticsearch Guide [7.17] | Elastic
