These authentication details are used while generating the CLI or YAML file for the collector.
What is cataloged
The collector catalogs the following information.
Object | Information cataloged |

Databases | Name, Identifier, Description, Database Connection Type |
Database tables | Name, Identifier |
Database columns | Name, Identifier |
Projects | Name, Description |
Workbooks | Name, Description, Creator Email, Creator Name, Creator Tableau User, Preview Image, and Workbook URL Note: Unpublished workbooks are not harvested. This is because the Tableau REST APIs do not return the objects if they are not published. |
Dashboards | Name, Creator Email, Creator Name, Creator Tableau User, Preview Image, and Dashboard URL Note: Unpublished dashboard are not harvested. This is because the Tableau REST APIs do not return the objects if they are not published. |
Views | Name, Creator Email, Creator Name, Creator Tableau User, Number of Views, Number of Favorites, Preview Image, and View URL Note: Unpublished views are not harvested. This is because the Tableau REST APIs do not return the objects if they are not published. |
Fields | Name, Identifier, Description |
Calculated fields | Name, Identifier, Description, Calculation Formula |
Dimensions | Name, Identifier, Description |
Measures | Name, Identifier, Description |
Metrics | Name, Identifier, Creator, Creation Date, Modified Date, Metrics UrlField Data Type, Field Format, Field Type |
Custom SQL tables | Name, Identifier, Description, Query |
Embedded data sources | Name, Identifier |
Published data sources | Name, Identifier, Description |
Relationships between objects
By default, the harvested metadata includes catalog pages for the following resource types. Each catalog page has a relationship to the other related resource types. If the metadata presentation for this data source has been customized with the help of the data.world Solutions team, you may see other resource pages and relationships.

Lineage for Tableau
The collector does not support harvesting cross-system lineage when Tableau reports connect to a source system using ODBC connections.
Object | Lineage available |
|---|---|
Database columns and tables | Fields that use database columns and tables |
Dashboards | Fields and tables that dashboards source their data from |
Views | Fields and tables that views source their data from |
Fields | Columns, tables, and other fields that a field uses its data from |
Embedded data sources | Published data sources |
Supported cross-system lineage
The currently supported data sources for cross-system lineage are:
Postgres
Snowflake
BigQuery
Redshift
Important
While other data sources are not formally supported, running the collector for those sources may still enable you to view cross-system lineage between TabIeau and these sources.
Important things to note about improving the performance of collector runs
Depending on the size of your Tableau instance, you may want to exclude or include specific resources from your catalog.
Exclude object types: Use the --tableau-exclude parameter to exclude harvesting of certain object types. The supported object types are: View, Dashboard, Database, PublishedDataSource, EmbeddedDataSource, CalculatedField, ColumnField, BinField, GroupField, DatasourceField, CustomSQLTable, Metric
Filter to specific Tableau site: Use the --tableau-site parameter to filter to a specific site.
Filter to specific Tableau projects: Use the --tableau-project parameter to harvest from multiple tableau projects. Use the parameter multiple times for multiple projects.
Filter out specific Tableau projects: Use the --tableau-exclude-project parameter to skip harvesting from multiple tableau projects. Use the parameter multiple times for multiple projects.
GraphQL page size: Use the --tableau-graphql-page-size parameter to adjust the GraphQL page size. The maximum page size is 1000.
Increase Docker resources: If you run into out of memory errors, increase the memory on the machine running the collector, or increase the java heap size when running a jar file, or use filtering.
