View source for Telemetry/Custom dashboards with re:dash

==Introduction==
Re:dash allows you to connect to various data sources via an interactive SQL frontend. You can then share your queries with peers, create visualizations, or combine these into an automatically updating dashboard.

Check it out at [sql.telemetry.mozilla.org sql.telemetry.mozilla.org]. re:dash is also known as stmo, an abbreviation of it's URL.

==Available Data Sources==

re:dash is data source agnostic. As such we have many different data sources available, where each will have their own tables to query from.

To choose a different data source, select it from the dropdown next to "Data Source". To see what tables are available, simply select the data source and execute <code>show tables</code>. Some data sources will have the tables and schemas show up in a table to the left of the query writing field.

===Presto===

We have a variety of datasets available for querying. [https://wiki.mozilla.org/Telemetry/Available_Telemetry_Datasets_and_their_Applications Full Documentation]

===Google Sheets===

To access a Google Sheet from re:dash:
* Share the spreadsheet with "gspread@pipeline-sql-prod.iam.gserviceaccount.com".
