Management API: Optimize collection view performance by eliminating N+1 patterns by AndyButland · Pull Request #21684 · umbraco/Umbraco-CMS

AndyButland · 2026-02-09T10:55:37Z

Summary

Eliminates multiple N+1 query patterns in the collection view (list view) pipeline. Each optimization replaces per-item service calls with single batched operations. These will often be returning cached data, but nevertheless, there's some overhead regarding scopes we can avoid even in these cases:

Permissions: Replaced per-item GetPermissionsForPath with a single batch GetPermissions call across all unique path node IDs.
IsProtected: Replaced per-item IsProtected calls with a single GetAll() query + in-memory path matching.
GetPathKeys: Computes ancestor path keys once for collection siblings (shared parent) instead of per item.
Schedule flags: Eliminated redundant GUID-to-int conversions in HasScheduleFlagProvider.
User profiles: Pre-resolves all unique Creator/Writer names via a single GetUsersById batch call and passes them through MapperContext, replacing per-item GetProfileById calls.

Impact

Once these were in place, with a setup using a collection view over a document set of 10000+ items, I could see significant improvements. This will vary depending on factors such as database latency, hardware etc., but in my tests there was a ~23% measured improvement in response time for content collection API requests.

Testing

Verify collection view render as before, including the filtering out of documents that the user doesn't have permission to see.

…ermissions query across all unique path node ids.

…ixed constructors.

… and in-memory path matching. Compute shared ancestor path keys once for collection siblings instead of per item.

Pull request overview

This PR targets the Management API “collection view” pipeline, removing several N+1-style per-item service calls by switching to batched lookups and by passing pre-resolved data through MapperContext.Items during mapping.

Changes:

Batch-resolve creator/writer display names and inject them into mapping via MapperContext to avoid per-item GetProfileById calls.
Replace schedule flag population to use a key-keyed schedule lookup (GetContentSchedulesByKeys) and obsolete the old id-keyed API.
Optimize permission filtering by batching permission retrieval across all unique node IDs in the paths being authorized.

Updated [Umbraco.Cms.Persistence.Sqlite](https://github.com/umbraco/Umbraco-CMS) from 17.2.2 to 17.3.0. <details> <summary>Release notes</summary> _Sourced from [Umbraco.Cms.Persistence.Sqlite's releases](https://github.com/umbraco/Umbraco-CMS/releases)._ ## 17.3.0 ## Upgrade Notes In 17.3 we have upgraded our dependency on `MailKit` to 4.15.1. This is a minor version update, but we found a few changes we had to make in core to accommodate changes to nullability constraints. Unless using methods of this library, or it's transitive dependency `MimeKit`, it's unlikely projects will be affected. The update is necessary though, as the version we previously depended on now has a security vulnerability raised against it. We have made a change to how we handle redirects which brings a significant performance improvement for publish time on large sites, when documents with many descendent nodes are published. If you have custom URL providers you should review this change, as there are some [very rare cases](umbraco/Umbraco-CMS#22091 (comment)) where you'll need to adjust to ensure descendent redirects are correctly handled. Note also that we now auto-generate HMAC secret key for new installs. This has been applied to make Umbraco more secure by default, but it's not been forced for upgrades. ## What's Changed Since 17.3.0-rc3 **Full Changelog**: umbraco/Umbraco-CMS@release-17.3.0-rc3...release-17.3.0 ## What's Changed Since 17.3.0-rc2 ### 📦 Dependencies * Dependencies: Update Microsoft packages to latest patch and fix HybridCache ParseFault with Redis by @AndyButland in umbraco/Umbraco-CMS#22278 ### 🐛 Bug Fixes * Examine: Fix DocumentUrlService not initialized during Examine indexing after package upgrade by @AndyButland in umbraco/Umbraco-CMS#22243 * Unattended Upgrades: Rebuild routing caches after background migrations to fix unrouteable document URLs by @AndyButland in umbraco/Umbraco-CMS#22269 * Migrations: Fix NPoco auto-select breaking re-trust FK migration by @AndyButland in umbraco/Umbraco-CMS#22270 **Full Changelog**: umbraco/Umbraco-CMS@release-17.3.0-rc2...release-17.3.0-rc3 ## What's Changed Since 17.3.0-rc1 ### 🐛 Bug Fixes * Migrations: Fix re-trust constraints migration targeting non-Umbraco tables and transaction failure (closes #22227) by @AndyButland in umbraco/Umbraco-CMS#22229 * Distributed Locking: Add ROWLOCK hint to prevent cross-row contention on umbracoLock table (closes #22113) by @AndyButland in umbraco/Umbraco-CMS#22126 * Application URLs: Prevent back office hosts being overwritten in a shared database setup (closes #16741) by @matthewcare in umbraco/Umbraco-CMS#22160 * Migrations: Fix property detection for invariant content types with culture-varying compositions (closes #22159) by @AndyButland in umbraco/Umbraco-CMS#22167 * Migrations: Fix package migrations not running after fresh install with packages (closes #22202) by @AndyButland in umbraco/Umbraco-CMS#22204 **Full Changelog**: umbraco/Umbraco-CMS@release-17.3.0-rc...release-17.3.0-rc2 ## What's Changed Since the Previous Version (17.2.2) ### 🙌 Notable Changes * Templates: Add optional Central Package Management support to UmbracoProject and UmbracoExtension templates by @NguyenThuyLan in umbraco/Umbraco-CMS#21641 * Service registration: Allow running Umbraco with different combinations of backoffice, website and delivery API (closes #21622) by @AndyButland in umbraco/Umbraco-CMS#21630 * Imaging Configuration: Auto-generate HMAC secret key for new installs by @AndyButland in umbraco/Umbraco-CMS#21976 * Migrations: Run unattended upgrades in background, add liveness/readiness health probes (closes #21987) by @AndyButland in umbraco/Umbraco-CMS#22020 ### 💥 Breaking Changes * Dependencies: Update MailKit to 4.15.1 by @AndyButland in umbraco/Umbraco-CMS#22028 ### 📦 Dependencies * Bump lodash from 4.17.21 to 4.17.23 in /tests/Umbraco.Tests.AcceptanceTest in the npm_and_yarn group across 1 directory by @dependabot[bot] in umbraco/Umbraco-CMS#21519 ...
