Mapping is a mechanism of Elasticsearch to be performed on documents and fields. It is responsible for storing and indexing the documents and their fields in the Elasticsearch database. Elasticsearch allows users to perform mapping on fields by defining datatype for them.
For example, - string datatype for name or number datatype for age, etc.
There are two types of mapping, i.e., Static mapping and Dynamic mapping.
Static mapping is a type of mapping which is done by users at the time of index creation. In comparison, Dynamic mapping is automatically done for the tables by the Elasticsearch.
