If you’re new to Unstructured, read this note first.Before you can create a destination connector, you must first sign up for Unstructured. After you sign up, the Unstructured user interface (UI) appears, which you use to create the destination connector.After you create the destination connector, add it along with a source connector to a workflow. Then run the worklow as a job. To learn how, try out the hands-on UI quickstart or watch the 4-minute video tutorial.You can also create destination connectors with the Unstructured API. Learn how.If you need help, reach out to the community on Slack, or contact us directly.You are now ready to start creating a destination connector! Keep reading to learn how.

      CREATE TABLE <catalog-name>.<schema-name>.elements (
   "type" varchar,
   "element_id" varchar,
   "text" varchar,
   "file_directory" varchar,
   "filename" varchar,
   "languages" array(varchar),
   "last_modified" double,
   "page_number" varchar,
   "filetype" varchar,
   "url" varchar,
   "version" varchar,
   "record_locator" varchar,
   "date_created" double,
   "date_modified" double,
   "date_processed" double,
   "filesize_bytes" bigint,
   "points" varchar,
   "system" varchar,
   "layout_width" bigint,
   "layout_height" bigint,

)
WITH (
   delete_mode = 'copy-on-write',
   format = 'PARQUET',
   format_version = '2'
)
      Note that incoming elements that do not have matching column names will be dropped upon record insertion. For example, if the incoming data has an element named sent_from and there is no column named sent_from in the table, the sent_from element will be dropped upon record insertion. You should modify the preceding sample table creation statement to add columns for any additional elements that you want to be included upon record insertion.
