Table Described

The Sync team's telemetry goes through our data pipeline and lands in Presto to be explored in Re:Dash. Below is a description of the data available in the sync_summary table.

Field Names	Data Type	Description
app_build_id	varchar	Firefox build ID (e.g. 20160801085519)
app_display_version	varchar	Firefox version (e.g. 50.0a2)
app_name	varchar	Platform?
app_version	varchar	What's the difference with app_display_version?
uid	varchar	Hashed Sync/FxA ID
deviceid	varchar	Browser profile id? Not currently captured.
when	bigint	Linux time stamp of when sync occurred. Make sure to put in "quotes" since when is a reserved SQL word.
took	bigint	Time it took to Sync?
failurereason	row(name varchar, value varchar)	Sync failure reason
status	row(sync varchar, service varchar)	??
why	varchar	Always null because XYZ and is meant for ABC

  FROM sync_summary 
  WHERE failurereason IS NOT NULL
)

SELECT

GROUP BY name
