The clients_daily table is intended as the first stop for asking questions about how people use Firefox. It should be easy to answer simple questions. Each row in the table is a (client_id, activity_date) and contains a number of aggregates about that day's activity.

Contents

Many questions about Firefox take the form "What did clients with characteristics X, Y, and Z do during the period S to E?" The clients_daily table is aimed at answer those questions.

Background and Caveats

The rows in the table are based on activity date rather than submission date, so there is a somewhat higher processing delay than for some other datasets. It is expected that the latest "day" available in this table is more than one day ago.

Accessing the Data

The data is stored as a parquet table in S3 at the following address.

s3://telemetry-parquet/clients_daily/v5/

The clients_daily table is accessible through re:dash using the Athena data source. It is also available via the Presto data source, though Athena should be preferred for performance and stability reasons.

Here's an example query.
