Question About Table History Discrepancy in Lakehouse
Hi stellahe102,
Thank you for reaching out to the Microsoft Fabric Forum Community.The discrepancy where two shortcut tables retain only 30 days of parquet files is likely due to VACUUM operations or predictive optimization on the source tables in the other workspace, limiting their history. Since shortcuts reference source data, maintenance like VACUUM with a 30-day retention (e.g., delta.deletedFileRetentionDuration = interval 30 days) affects their history.
Steps to Investigate:
- Check source table properties: SHOW TBLPROPERTIES source_table_name for delta.deletedFileRetentionDuration.
- Review source workspace for VACUUM jobs.
- Coordinate with the source workspace owner to align retention policies.
Please refer below official documentation:
