issue #7567 : VFS support for Databricks UC Volumes (Files API)#7575
Merged
Conversation
Add a named Databricks VFS connection (scheme = metadata name, auth via Databricks Connection, optional root path) and Commons VFS provider over the workspace Files API for browse/read/write/list/mkdir/rename/delete. Extract RestDatabricksFilesClient for Jobs deploy and VFS; log Move Files exceptions with full stack; document Hop-side vs Spark path dialect.
…sed SVGs Replace the simplified connection icon with the Databricks brand mark and remove unused job-run/job-wait/logo SVG duplicates.
Publish MainSpark exported metadata for named VFS schemes, cache Files API last_modified on VFS children, and skip mtime pre-filter only when known so Caching File locations on Volumes list correctly in the GUI. Document the Caching File + db-volume pattern with screenshots and cross-links from VFS, execution location, and Execution Information.
