Unity Catalog system tables (table_lineage, column_lineage) not populated

Hi community,

We have enabled Unity Catalog system schemas (including `access`) more than 24 hours ago in sandbox. The schemas are showing ENABLE_COMPLETED, and other system tables (like query) are working fine.

However, both `system.access.table_lineage` and `system.access.column_lineage` tables are still empty after one day.

Context:
- We are using Unity Catalog-managed tables (not Hive metastore).
- We ran multiple SQL queries (CREATE TABLE AS SELECT, INSERT INTO, SELECT * FROM).
- We verified that query history and other access tables are working.

- We created tables after lineage is enabled too.

What would be reason of it.

I'm also running into a similar issue where our system.access.column_lineage and system.access.table_lineage tables are no longer visibile.

This appears to be resolved on my end. Not sure if they're related.

Hi @yavuzmert, is this still an issue? Are you seeing lineage for those tables in the UI? One thing to remember about system tables is that their data is updated throughout the day. Usually, if you don't see a log for a recent event, check back later.
