BigQuery Usage & Optimization Properties
Usage and cost optimization properties are derived from BigQuery’s query logs, specifically from the INFORMATION_SCHEMA.JOBS and INFORMATION_SCHEMA.JOBS_BY_PROJECT views.

Read properties capture activity from SQL statements such as SELECT. These properties apply to all BigQuery table subtypes, and some also apply at the column level.

tables, base_tables, temporary tables, materialized_views
average_read_bytes_processed_14d average_read_bytes_processed_30d average_read_bytes_processed_60d

tables, base_tables, temporary tables, materialized_views
total_read_runtime_14d total_read_runtime_30d total_read_runtime_60d
Total runtime of read queries (SELECT queries) referencing the resource over the last 14/30/60 days.
tables, base_tables, temporary tables, materialized_views
distinct_users_14d distinct_users_30d distinct_users_60d
Number of distinct users who queried (SELECT queries) the resource over the last 14/30/60 days.
tables, base_tables, temporary tables, materialized_views, columns
Write Properties
Write-related properties capture activity from SQL statements such as INSERT, UPDATE, DELETE, and MERGE. These metrics apply to both tables and materialized views.

Total number of write operations (INSERT, UPDATE, DELETE, MERGE) involving the table in the last 14/30/60 days.
tables, base_tables, temporary tables, materialized_view
total_write_slots_14d total_write_slots_30d total_write_slots_60d
Total slots consumed by write operations (INSERT, UPDATE, DELETE, MERGE) involving the table in the last 14/30/60 days.
tables, base_tables, temporary tables, materialized_view
average_write_slots_14d average_write_slots_30d average_write_slots_60d
Average slots consumed by write operations (INSERT, UPDATE, DELETE, MERGE) involving the table in the last 14/30/60 days.
tables, base_tables, temporary tables, materialized_view
total_write_bytes_processed_14d total_write_bytes_processed_30d total_write_bytes_processed_60d
Total number of bytes processed by write queries (INSERT, UPDATE, DELETE, MERGE) involving the table over the last 14/30/60 days.

Storage Properties
Storage properties reflect the current size of the table as stored in BigQuery. They are used to represent storage utilization and are applicable to all table types.

upstream
table
For views, this is based on analyzing the SQL defining the view. For tables, the lineage is based on analyzing the queries in the log. Euno considers all write queries in the last 7 days to infer the lineage.
column
upstream_fields
column
For views, this is based on analyzing the SQL defining the view. For tables, the lineage is based on analyzing the queries in the log. Euno considers all write queries in the last 7 days to infer the lineage.
table
upstream
google_sheet
For external tables with format = 'GOOGLE_SHEETS', this relationship connects the BigQuery table to the Google Sheet it references.
Known Limitations
For columns of type STRUCT, column-level lineage (upstream_fields relationships) is tracked only at the column level, from the source BigQuery column to the target BigQuery column. Lineage is not captured for individual nested keys within the STRUCT.
Hex Projects
Properties
name
The name of the Hex project
type
always hex_project
subtype
always hex_project
native_id
The unique project ID from Hex
Lineage Information
The BigQuery integration tracks which BigQuery tables and columns are accessed by each Hex project through analysis of query history. This enables:
Data Dependencies: Understand how Hex projects depend on specific BigQuery resources.
Access Patterns: Identify which tables and datasets are most frequently accessed by Hex projects.
Impact Analysis: Determine which Hex projects might be affected by changes to BigQuery resources.
