- Execute RefreshConnections asyncronously - Add connection_state table to indicate the loading state of connections - Optimise RefreshConnections by cloning connection schemas - Add locking to ensure only a single instance of RefreshConnections runs - Start executing queries without waiting for connections to load, add smart error handling to wait for required connection - Optimise autocomplete for high connection count - Autocomplete and inspect data available before all conections are refreshed - Update file watcher to respond to CHMOD, so thaat it pickes up deletion of file contents Closes #3394 Closes #3267
