<!-- Add the related story/sub-task/bug number, like Resolves #123, or remove if NA --> **Related issue:** Resolves #42156 The core change: instead of loading AppConfig, HostFeatures, TeamMDMConfig, and rebuilding the detail query map **independently inside each call** to `directIngestDetailQuery` and `ingestDetailQuery` (so ~2N times per check-in with N detail results), we load everything **once** into a `hostDetailQueryConfig` struct and pass it through. ## Before ``` SubmitDistributedQueryResults loop: for each query result: → ingestQueryResults → directIngestDetailQuery: loads AppConfig, HostFeatures, TeamMDMConfig, builds detail query map → ingestDetailQuery: loads AppConfig, HostFeatures, TeamMDMConfig, builds detail query map after loop: loads AppConfig for labels/policies loads AppConfig AGAIN for deferred host save ``` ## After ``` SubmitDistributedQueryResults loop: on first detail query result: → loadHostDetailQueryConfig: loads AppConfig, HostFeatures, TeamMDMConfig, builds detail query map ONCE for each query result: → ingestQueryResults (receives pre-loaded config) → directIngestDetailQuery: just looks up the query in the cached map → ingestDetailQuery: just looks up the query in the cached map after loop: loads AppConfig once for labels/policies/deferred host save ``` The detail config is **lazy-loaded** — if a check-in only has label/policy results and no detail queries, the HostFeatures/TeamMDMConfig calls are skipped entirely. ## Other changes bundled in 1. **`serialUpdateHost`** now receives the request context and uses `context.WithoutCancel(ctx)` instead of `context.Background()`, so the background goroutine preserves OTEL traces and logging context without being subject to request cancellation. 2. **Deferred save host** at the end of `SubmitDistributedQueryResults` reuses the already-loaded AppConfig instead of loading it a third time. The old code silently skipped the host save if that third load failed. # Checklist for submitter If some of the following don't apply, delete the relevant line. - [x] Changes file added for user-visible changes in `changes/`, `orbit/changes/` or `ee/fleetd-chrome/changes`. ## Testing - [x] QA'd all new/changed functionality manually - Ran a local load test with osquery perf <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Performance** * Optimized distributed query result processing by preloading configuration once per request instead of repeatedly per query result, reducing redundant database calls and improving overall query performance. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

Open-source platform for IT and security teams with thousands of computers. Designed for APIs, GitOps, webhooks, YAML, and humans.
What's it for?
Organizations like Fastly and Gusto use Fleet for vulnerability reporting, detection engineering, device management (MDM), device health monitoring, posture-based access control, managing unused software licenses, and more.

To see what kind of data you can use Fleet to gather, check out the table reference documentation.
Out-of-the-box policies
Fleet includes out-of-the box support for all CIS benchmarks for macOS and Windows, as well as many simpler queries.
Take as much or as little as you need for your organization.

- Linux (all distros)
- macOS
- Windows
- Chromebooks
- Amazon Web Services (AWS)
- Google Cloud (GCP)
- Azure (Microsoft cloud)
- Data centers

Lighter than air
Fleet is lightweight and modular. You can use it for security without using it for MDM, and vice versa. You can turn off features you are not using.
Openness
Fleet is dedicated to flexibility, accessibility, and clarity. We think everyone can contribute and that tools should be as easy as possible for everyone to understand.
Good neighbors
Fleet has no ambition to replace all of your other tools. (Though it might replace some, if you want it to.) Ready-to-use, enterprise-friendly integrations exist for Snowflake, Splunk, GitHub Actions, Vanta, Elastic Jira, Zendesk, and more.
Fleet plays well with Munki, Chef, Puppet, and Ansible, as well as with security tools like Crowdstrike and SentinelOne. For example, you can use the free version of Fleet to quickly report on what hosts are actually running your EDR agent.
Free as in free
The free version of Fleet will always be free. Fleet is independently backed and actively maintained with the help of many amazing contributors.
Longevity
The company behind Fleet is founded (and majority-owned) by true believers in open source. The company's business model is influenced by GitLab (NYSE: GTLB), with great investors, happy customers, and the capacity to become profitable at any time.
In keeping with Fleet's value of openness, Fleet Device Management's company handbook is public and open source. You can read about the history of Fleet and osquery and our commitment to improving the product.
Is it any good?
Fleet is used in production by IT and security teams with thousands of laptops and servers. Many deployments support tens of thousands of hosts, and a few large organizations manage deployments as large as 400,000+ hosts.
Chat
Please join us in MacAdmins Slack or in osquery Slack.
The Fleet community is full of kind and helpful people. Whether or not you are a paying customer, if you need help, just ask.
Contributing
The landscape of cybersecurity and IT is too complex. Let's open it up.
Contributions are welcome, whether you answer questions on Slack / GitHub / StackOverflow / LinkedIn / Twitter, improve the documentation or website, write a tutorial, give a talk at a conference or local meetup, give an interview on a podcast, troubleshoot reported issues, or submit a patch. The Fleet code of conduct is on GitHub.
