Sample queries — to be found in the Description field of the schema Public
Documentation in the form of Alation articles that explains the Alation Analytics V2 schema and some of the best practices for writing queries:

The qli_events Table¶

The table qli_events is intended to provide a comprehensive view of data consumption at the data source, query, and user levels. Users need to be aware of these limitations:

The qli_events table is activated on demand. Please reach out to your account executive or Alation Support for activation. After activation, the data will become available after an ETL run.
In versions 2024.1.3 to 2024.3.1, the qli_events table was limited to supporting one month of historical data upon activation, capped at 30 million rows. Starting with version 2024.3.2, enhancements to the pipeline have increased the capacity to approximately 120 million records per month, allowing for extracting four times more data than the previous limit for the same duration.
After activation, the table supports up to 90 days of additional data over the historical data populated at the time of activation.
Currently, the qli_events data is only in General Availability (GA) for Snowflake data sources. We aim to expand the General Availability to include more data sources in future releases.
