# Tableau
For context on getting started with ingestion, check out our [metadata ingestion guide](../README.md).
Note that this connector is currently considered in `BETA`, and has not been validated for production use.
## Setup
To install this plugin, run `pip install 'acryl-datahub[tableau]'`.
See documentation for Tableau's metadata API at https://help.tableau.com/current/api/metadata_api/en-us/index.html
## Capabilities
This plugin extracts Sheets, Dashboards, Embedded and Published Data sources metadata within Workbooks in a given project
on a Tableau Online site. This plugin is in beta and has only been tested on PostgreSQL database and sample workbooks
on Tableau online.
Tableau's GraphQL interface is used to extract metadata information. Queries used to extract metadata are located
in `metadata-ingestion/src/datahub/ingestion/source/tableau_common.py`
- [Dashboard](#Dashboard)
- [Sheet](#Sheet)
- [Embedded Data source](#Embedded-Data-Source)
- [Published Data source](#Published-Data-Source)
- [Custom SQL Data source](#Custom-SQL-Data-Source)
### Dashboard
Dashboards from Tableau are ingested as Dashboard in datahub. <br/>
- GraphQL query <br/>
```
{
workbooksConnection(first: 15, offset: 0, filter: {projectNameWithin: ["default", "Project 2"]}) {
nodes {
id
name
luid
projectName
owner {
username
}
description

dashboards {
id

path
createdAt
updatedAt
sheets {
id
name
}
}
}
pageInfo {
hasNextPage
endCursor
}
totalCount
}
}
```
### Sheet
Sheets from Tableau are ingested as charts in datahub. <br/>
- GraphQL query <br/>
```
{
workbooksConnection(first: 10, offset: 0, filter: {projectNameWithin: ["default"]}) {
.....
sheets {
id
name

}
}
}
.....
}
}
```
### Embedded Data Source
Embedded Data source from Tableau is ingested as a Dataset in datahub.
- GraphQL query <br/>
```
{
workbooksConnection(first: 15, offset: 0, filter: {projectNameWithin: ["default"]}) {
nodes {
....
embeddedDatasources {
__typename

}
}
upstreamDatasources {

}
}
```
### Published Data Source
Published Data source from Tableau is ingested as a Dataset in datahub.
- GraphQL query <br/>
```
{
publishedDatasourcesConnection(filter: {idWithin: ["00cce29f-b561-bb41-3557-8e19660bb5dd", "618c87db-5959-338b-bcc7-6f5f4cc0b6c6"]}) {

```
### Custom SQL Data Source
For custom sql data sources, the query is viewable in UI under View Definition tab. <br/>
- GraphQL query <br/>
```
{
customSQLTablesConnection(filter: {idWithin: ["22b0b4c3-6b85-713d-a161-5a87fdd78f40"]}) {
nodes {

... on EmbeddedDatasource {
workbook {

}
}
}
}
}
tables {
id

schema
connectionType
}
}
}
}
```
## Quickstart recipe
Check out the following recipe to get started with ingestion! See [below](#config-details) for full configuration options.
For general pointers on writing and running a recipe, see our [main recipe guide](../README.md#recipes).
```yml
source:
type: tableau
config:
# Coordinates
connect_uri: https://prod-ca-a.online.tableau.com
site: acryl
projects: ["default", "Project 2"]
# Credentials
username: username@acrylio.com
password: pass
token_name: Acryl
token_value: token_generated_from_tableau
# Options
ingest_tags: True
ingest_owner: True
default_schema_map:
mydatabase: public
anotherdatabase: anotherschema
sink:
# sink configs
```
## Config details
| Field | Required | Default | Description |
|-----------------------|----------|-----------|--------------------------------------------------------------------------|
| `connect_uri` | ✅ | | Tableau host URL. |
| `site` | ✅ | | Tableau Online Site |
| `env` | | `"PROD"` | Environment to use in namespace when constructing URNs. |
| `username` | | | Tableau user name. |
| `password` | | | Tableau password for authentication. |
| `token_name` | | | Tableau token name if authenticating using a personal token. |
| `token_value` | | | Tableau token value if authenticating using a personal token. |
| `projects` | | `default` | List of projects |
| `default_schema_map`* | | | Default schema to use when schema is not found. |
| `ingest_tags` | | `False` | Ingest Tags from source. This will override Tags entered from UI |
| `ingest_owners` | | `False` | Ingest Owner from source. This will override Owner info entered from UI |
*Tableau may not provide schema name when ingesting Custom SQL data source. Use `default_schema_map` to provide a default
schema name to use when constructing a table URN.
### Authentication
Currently, authentication is supported on Tableau Online using username and password
and personal token. For more information on Tableau authentication, refer to [How to Authenticate](https://help.tableau.com/current/api/metadata_api/en-us/docs/meta_api_auth.html) guide.
## Compatibility
Tableau Server Version: 2021.4.0 (20214.22.0114.0959) 64-bit Linux <br/>
Tableau Pod: prod-ca-a
