In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Type Attributes), this format adds the format-specific attributes described in this topic.
Features read from Elasticsearch consist of geometry and a series of attribute values. The feature type of each Elasticsearch feature is as defined in the Reader Feature Type parameters.
Features written to Elasticsearch have the destination database as their feature type, and attributes as defined in the Elasticsearch Writer Feature Type Parameters.
Elasticsearch attribute names and values support full UTF-8.
Elasticsearch attribute types are listed in Elasticsearch Writer: User Attributes.
