Reply to Slow rendering List backed by SwiftData @Query
So basically, could I build the Photos app (or something like it) in SwiftData. Seems to be no. Because Query cannot handle anything remotely close to the thousands of displayed objects. I tested a manual fetch on context. Performed in milliseconds as expected. But anything in Query, completely fails with like 10 seconds when it gets bad

@xmollv this is wild. I added a little button to your app that simply creates a new item. The button hangs for over 2 seconds because the update takes you know however many milliseconds but then the query kicks in on the main thread and blocks everything. Its ridiculously bad. @DTS Engineer can you revisit this? We have submitted issues, but this is ridiculously problematic

This is still an issue. What should we do? Really just paginate?
