Dynamic mappings and templates
The previous topic described how we can define type mapping if the mapping generated automatically by ElasticSearch is not sufficient. Now let's go one step back and see how automatic mapping works. Knowledge about this prevents surprises during development of your applications and let's you build more flexible software. In this second case, if sometimes our application grows and automatically generates new indexes (for example, for storing a massive number of time-based events), it is more convenient to adjust the mechanism of determining the data types. Also, if an application has many indexes, the possibility of defining the mapping templates is very handy.
