Presto

Extracts tables from every catalog and schema on a Presto server. It emits table entities with column details.

Usage

source:
  name: presto
  scope: my-scope
  config:
    connection_url: "http://user:pass@localhost:8080"
    exclude:
      catalogs:
        - memory
        - system
        - tpcds
        - tpch

Configuration

Key	Type	Description	Required
`connection_url`	`string`	HTTP URL for the Presto server, with user and password if needed.	Yes
`exclude.catalogs`	`[]string`	Catalog names to skip during extraction.	No

Output

Emits table entities with URN pattern urn:presto:{scope}:table:{catalog}.{schema}.{table}.

Notable properties:

columns — list of columns with name, data_type, is_nullable, and description (when a comment exists)

This extractor does not emit edges.

Notes

Built-in catalogs like memory, system, tpcds, and tpch are not excluded by default. Add them to exclude.catalogs if you do not want them.
