⚡ Bolt: Optimize Room Sync with Batch Inserts - #94
Conversation
* Replaced individual `db.dao().insert()` loops with `db.dao().insertBatch()` calls for Books and Bookmarks sync operations.
* Wrapped batched insertions in `db.withTransactionCompat { chunked(900).forEach { ... } }` to eliminate O(N) SQLite transaction overhead.
* Documented the performance improvement in `.jules/bolt.md`.

💡 What:
Replaced O(N) individual
insertcalls inpullBooksandpullBookmarkssync logic with chunkedinsertBatchinside a single transaction.🎯 Why:
Blindly inserting entities in a loop utilizing
OnConflictStrategy.REPLACEcreated significant SQLite transaction overhead, slowing down large synchronization processes.📊 Impact:
Drastically reduces disk I/O and SQLite churn, resulting in faster and more efficient syncing, particularly for large collections of bookmarks and books.
🔬 Measurement:
Compare the overall duration of the sync worker before and after this change, or trace SQLite disk write metrics during
