Query Latency from Filter Complexity
warninglatencyUpdated Feb 6, 2026
REST and gRPC query durations (rest_responses_duration_seconds, grpc_responses_duration_seconds) increase when filters are applied, indicating unoptimized payload indexing or missing indexes.
Sources
How to detect:
Compare query duration histograms between filtered and unfiltered queries (track db.qdrant.has_filter attribute from traces). Monitor collection_hardware_metric_payload_index_io_read for excessive reads.
Recommended action:
Create payload indexes on frequently filtered fields. Consider enabling indexed_only mode if collection_indexed_only_excluded_points is acceptable. Review filter cardinality and complexity.
