ElasticSearch, which is the world's most advanced search and analytics engine, brings the ability to make massive amounts of data usable in a matter of milliseconds. Use dynamic mapping and let elasticsearch "guess" the mapping; Fields and mapping types do not need to be defined before being used. I need to change field type, but I don't know how knowing that I'm using logstash for importing data from CSV file so I didn't specify the field type manually and I think the default value is a string, but I need to change it to long or integer, what is the command that allows updating mapping settings or at least fields type? Thank you!. You can also specify fields which will be indexed by the driver through the toSearchableArray method. When a match occurs, it is given to one or more alerts, which take action based on the match. We can use the put mapping command from Elasticsearch's REST API to define a document type. The Configuration API is a REST API that you can use to create and configure Amazon ES domains over HTTP. The first time a given key is indexed, Elasticsearch will determine an appropriate data type to use, create a mapping for that key, and index the field. You can configure Elasticsearch by creating an index template that maps string fields to the keyword type. Supposing you are using dynamic mapping (which is by default), the type of a field depends of the type of data present in the field of the first indexed document.
