Applicability
Unpinned upstream documentation accessed 2026-09-14; pin engine, extension and service versions before use.
Self-managed server deployment; Qdrant Cloud and Edge are outside this target.
Excludes: Runtime verification; Workload benchmarks and cost comparisons; Unlisted extensions, service tiers and deployment configurations
Recheck when
- Upstream version, license, API, service plan or storage topology changes.
Needs recheck · due
Verification plan
- Pin the target configuration and define workload fixtures, access and budget.
- With authorization, test concurrent writes and recovery against explicit correctness expectations.
- For vector workloads, measure filtered recall against an exact-search baseline and record index settings.

Capability claims · 5 / 17 sourced
Standing condition: these are documentation claims at the source capture date, with outcome “claimed”; no runtime execution is recorded. Dossier applicability and limitations apply throughout. Expand a row for its statement, specific scope and contradictions. Numbered citations resolve to the source locator and capture date below. Missing evidence means Unknown, not No. Sources are unpinned unless marked “Pinned”; this marks source stability, not stronger support or runtime verification. Reuse counts refer to claims in the full dossier; repeated citations do not represent independent sources.
Yes Documented within scope Partial Limited form of the feature No Explicit evidence of absence Unknown No evidence recorded. These are support assessments, not quality scores or runtime verification.
