Metadata Loader Categories

In this article you'll find detailed information about the loader categories and which exact information is extracted by each of the loaders we support. Each type differs in the object hierarchy, structure of the objects, and detail of the objects.

There are five types of the metadata loaders:
  • Database Loaders
  • File Loaders
  • Visualytics (Report) Loaders
  • Workflow Loader
  • Other Loaders

Database Loaders

Database loaders are used to harvest metadata about database objects such as database server (RDMS), catalog, schema, table/view/procedure, column. An example can be an Oracle database with all available objects, descriptions, and relationships within the objects in the database.
Connect supports database metadata loader for these technologies: Teradata, Snowflake, Apache Hive, IBM DB2, Exasol, Oracle, Microsoft SQL Server, MySQL, SAP HANA, Amazon Redshift, HP Vertica, PostgreSQL, Apache Impala.

File Loaders

File loaders are used to harvest metadata about file systems such as file bucket or folder with subfolder structure, individual files, sheets (when available e.g. on xlsx file), and columns on files you can parse for the structural information (xls(x), csv, yxdb, avro …). For files with structure you can store also profiling information such as number of rows, not nulls, blanks, uniqueness, and average length.
Connect supports file metadata loader for the following technologies: Amazon S3, Apache Hadoop, Microsoft Azure Data Lake, Files loader (windows shared drives).

Visualytics (Report) Loaders

Visualytics are used to harvest metadata from reporting platforms such as report workbook, worksheet, datasource, and detailed columns.
Connect supports visualytics metadata loader for these technologies: Tableau, Microsoft PowerBI, QlikView, Qlik Sense.

Workflow Loader

Workflow loader is used to harvest metadata from the Alteryx Gallery. Connect supports only AYX Gallery Loader.

Other Loaders

This category describes loaders that don't belong to any of the above-mentioned categories, such as:

    • Alteryx Promote loader is used to harvest metadata about Promote models published on a Promote server.
    • Microsoft Azure Data Catalog loader is used to exchange metadata from Azure Data Catalog about databases, files, and business terms.
    • Salesforce loader (without data profiling) is used to harvest metadata from the Salesforce application.
