auto-save-dual-debounce

A dual-debounce autosave system groups rapid edits into undoable batches while separately batching database writes to prevent undo history loss. This preserves word-level undo while persisting changes efficiently without thrashing the database.

Batching database writes for document persistence uses a second debounce layer that triggers at longer intervals than the first, accumulating rapid keystrokes into a single write to avoid thrashing while maintaining a responsive user experience.

Autosave overwrites undo states because it writes on every keystroke without batching. A dual-layer debounce groups rapid typing into meaningful undo batches first, then persists the active version without creating new undo states.

Yes, the debounce autosave approach works across desktop and mobile by using platform-specific flush-on-exit hooks and editor-agnostic integration. It handles multi-device editing and long-form documents effectively.

A dirty-state tracker monitors unsaved edits while platform-specific flush-on-exit hooks trigger a final save when the application closes. This ensures no pending changes are lost during background persistence or sudden exits.

Yes, the debounced save persists edits to the active version without creating new database versions. The Database Versioning service manages this alongside an UndoManager that handles batching for fine-grained undo workflows.
