Fully Dynamic Query Binding with ViewModel items

using var subscription = queryController.ItemsSource
    .AsChangeStream()
    .WhereItems(
        predicateState:         queryController.NameMatchingPattern,
        predicate:              static (nameMatchingPattern, item) => IItem.FilterByName(item, nameMatchingPattern),
        itemRefreshRequested:   static item => item.WhenPropertyChangeDetected(item => item.Name))
    .OrderItems(
        comparisonState:        queryController.OrderByColumn,
        comparison:             static (orderByColumn, x, y) => IItem.CompareByColumn(x, y, orderByColumn),
        itemRefreshRequested:   static item => item.WhenPropertyChangeDetected())
    .SliceItems(queryController.PageRange)
    .BindItems(bindingController.SourceItems);

Basically, I put together the most complicated scenario I could: Filter, Sort, and Page, with items that are fully mutable (meaning we need to handle single-item refreshes) and with observable state for all operators (meaning we need to handle full re-filter, re-sort, and re-page operations).

Each operator is implemented as a proof of concept, rather than optimally, using a plain collection to track upstream items, and a change-aware collection to track downstream items. E.G. the .WhereItems() operator has unfilteredItemStatesByKey and filteredItemsByKey.

Even with these naive implementations (.WhereItems() in particular is responsible for almost all of the bottlenecks, it performs very poorly with large resets), we can see drastic improvements over baseline DD.

Individual Operator Profiling

For each of this, I basically took the full query above and trimmed it down to just one operator. I then calculated "Adjusted" measurements for each benchmark by subtracting out the measurement from the equivalent "InitialResetOnly" benchmark (for "IntiialResetOnly" the "SubscriptionsOnly" measurement is subtracted), as a way to roughly eliminate the overhead from setup and binding, and estimate the impact of just the operator in question.

Keyed Filtering

using var subscription = queryController.ItemsSource
    .AsChangeStream()
    .WhereItems(
        predicateState:         queryController.NameMatchingPattern,
        predicate:              static (nameMatchingPattern, item) => IItem.FilterByName(item, nameMatchingPattern),
        itemRefreshRequested:   static item => item.WhenPropertyChangeDetected(item => item.Name))
    .Source
    .BindItems(bindingController.SourceItems);
