- Dynamic tables require the `monitor` privilege for metadata extraction. Without this privilege, dynamic tables will not be visible to DataHub.
- The underlying Snowflake views that we use to get metadata have a [latency of 45 minutes to 3 hours](https://docs.snowflake.com/en/sql-reference/account-usage.html#differences-between-account-usage-and-information-schema). So we would not be able to get very recent metadata in some cases like queries you ran within that time period etc. This is applicable particularly for lineage, usage and tags (without lineage) extraction.
- If there is any [ongoing Snowflake incident](https://status.snowflake.com/), we will not be able to get the metadata until that incident is resolved.
- Lineage extraction, when got directly from Snowflake access history, has some limitations, as documented [here](https://docs.snowflake.com/en/sql-reference/account-usage/access_history#usage-notes), [here](https://docs.snowflake.com/en/sql-reference/account-usage/access_history#usage-notes-column-lineage), and [here](https://docs.snowflake.com/en/sql-reference/account-usage/access_history#usage-notes-object-modified-by-ddl-column).
