This PR introduces a new environment variable
DATABRICKS_ASYNC_TOKEN_REFRESHto enable asynchronous token refresh in the Databricks SDK for Java. This feature improves performance by allowing token refresh operations to happen in the background, reducing latency for API calls.This change activates the asynchronous refresh capability that was previously added in #455. When enabled, stale tokens will trigger a background refresh while expired tokens will still block until a new token is fetched.
Note: Async token refresh for direct-to-dataplane access will be added in a separate PR.
How to Enable Async Token Refresh
You can enable async token refresh in two ways:
export DATABRICKS_ASYNC_TOKEN_REFRESH=trueThis setting will be automatically picked up by the SDK and applied to all token refresh operations.
How is this tested?
