Which does Spanner prioritize, high-priority tasks or non-priority tasks?

[ms4446 · Accepted solution]

In Spanner, high-priority tasks are prioritized over non-priority tasks. Spanner uses a priority system to manage various operations, where high-priority tasks, such as schema updates, backup and restore operations, and other critical system tasks, are given precedence over non-priority tasks like regular query execution or lower-priority background tasks. This ensures that critical operations are completed promptly, even if it means delaying or throttling lower-priority tasks.

This prioritization helps maintain the overall performance and consistency of the Spanner database, especially in environments with high workloads or during essential maintenance activities.
