# BigQuery Usage Data

## Table Activities in Euno

For resources of type table, and for supported sources (currently BigQuery), Euno displays key usage insights derived from BigQuery's query history and metadata, when made available to Euno (see the [BigQuery](/sources/data-warehouses/bigquery-integration.md) configuration section for details).

#### Usage Categories

**1. Table Read**

* Total number of `SELECT` queries referencing the table
* Cumulative query runtime (in hours/minutes)
* Total bytes processed from the table

**2. Table Write**

* Total number of DML queries (`INSERT`, `UPDATE`, `DELETE`, `MERGE`)
* Total number of materialized view or derived table refresh operations involving this table
* Cumulative write-related runtime
