Hi @JonLaRose 

Databricks provides specific consistency guarantees depending on whether you're dealing with managed or external tables, particularly in the context of multi-writer scenarios

Key Differences:

  • Control Over Storage: Databricks has full control over managed tables, allowing it to enforce stronger consistency guarantees, especially in multi-writer scenarios. In contrast, external tables rely on the external storage system, which may not support the same level of consistency.
  • Multi-Writer Scenarios: Managed tables offer better consistency in multi-writer scenarios due to Delta Lake's ACID properties. External tables, on the other hand, are more prone to issues like write conflicts and eventual consistency problems.
