To access format parameters, open the Feature Type Properties dialog by clicking the properties 
button on a feature type in the workspace. These parameters are applicable only to the selected feature type.
These parameters apply only to a selected feature type, not to the entire writer.
Tip: If a feature type parameter listed here conflicts with a writer-level parameter, then the writer parameter will be ignored and this feature type parameter will be used.
Table Settings: General
Table Handling
This parameter controls how the feature type handles destination tables. These options are available:
- Create If Needed: Create destination table if it does not exist. The writer uses the information within the FME workspace to automatically create Vector Feature tables as required. All tables will be created when the first input feature is processed. If no features are sent to a feature type, then the corresponding table will not be created.
- Drop and Create: Drop destination table if it exists, then create it. The writer will drop and re-create the table before writing any features to it. Tables will be overwritten when the first input feature is processed. If no features are sent to a feature type, then the corresponding table will not be overwritten.
- Use Existing: If the destination database does not exist, the translation will fail.
Database Creation
Use GeoJSON Specification
Specify whether to write GeoJSON features to the database. This parameter is only relevant if the database is being created.
Default: Yes
Advanced
Document Source
The source of JSON documents to write to the database.
- Feature: Documents will be created from features sent to the Cloudant Writer (which is the usual behavior).
- JSON Attribute: Documents will be created using JSON directly from an attribute, if possible.
Document ID
This parameter is enabled when the Document Source is Feature. It can be used to specify an attribute to use as the Document ID. Any features that contain that attribute will use its value as the JSON Document ID.
If not specified, the document ID will be automatically generated by the Cloudant service.
JSON Attribute
This parameter is enabled when the Document Source is JSON Attribute. It can be used to specify an attribute to use directly as the JSON document. Any features that contain the JSON attribute will be written using the JSON attribute value. Other features will be written as usual.
