For Presto, this data must be mapped into columns to allow queries against the data. A rule of thumb is to have the Elasticsearch JVM use no more than half of the available memory. Elasticsearch also creates a dynamic type mapping for any index that does not have a predefined mapping. You need to define these mappings and generate mapping files for the indexes defined. I keep my mappings and analyzers in separate JSON files, usually in a shared location, but if not on my windows/ubuntu machine within the project directory.
