Trino is a distributed SQL query engine designed to query large data sets distributed over one or more heterogeneous data sources. For more information, see https://trino.io/.

Early Preview connection: This connection is in early preview. It is read-only and available only in SaaS product editions. For more information on early previews, see Early Preview Connection Types.

Limitations and Requirements

NOTE: During normal selection or import of an entire table, you may encounter an error indicating a problem with a specific column. Since some tables require filtering based on a particular column, data from them can only be ingested using custom SQL statements. In this case, the problematic column can be used as a filter in the WHERE clause of a custom SQL statement to ingest the table.

  • For more information, please consult the CData driver documentation for the specific table.
  • For more information on using custom SQL, see Create Dataset with SQL.

NOTE: For filtering date columns, this connection type supports a set of literal functions on dates. You can use these to reduce the volume of data extracted from the database using a custom SQL query. For more information, see the pg_dateliteralfunctions.htm page in the driver documentation for this connection type.

  • Trino supports NoAuth and Basic (LDAP) authentication.

  • Trino has double PATH metadata, that is, Catalog and Schema. You can import tables only after the selection of Catalog and Schema. 

    trino/mysql/classicmodels
    
    

    Where, mysql is the catalog and classicmodels is the Schema.

  • While importing data through custom SQL, insert custom SQL statements as  SELECT * from catalog.schema.tableName.
