The Analytics Data Lake (ADL), or the Data Lake for short, is a large, analytics-oriented repository of data about Wikimedia projects (in industry terms, a data lake). All of the data it contains can be joined together.
- Traffic data -- webrequest, pageviews, unique devices ...
- Edits data -- Historical data about revisions, pages, and users [in beta as of 2017-04-07].
- Events data -- Eventlogging, eventbus and eventstreams data (raw, refined, sanitized)
- ORES scores -- Machine learning predictions [available as events as of 2020-02-27]
As the Data Lake matures, we will add any and all data and try to make it public as much as possible.
The Analytics cluster, which consists of Hadoop servers and related components, provides the infrastructure for the Data Lake.
