TS.QUERYLABELS example
This example demonstrates TSQueryLabels and TSQueryLabelValues, the
client bindings for the two forms of TS.QUERYLABELS (Redis 8.10+):
TSQueryLabels(ctx, filters)— the set of label names present on the matching time series (TS.QUERYLABELS LABELS [FILTER ...]).TSQueryLabelValues(ctx, label, filters)— the set of values assigned to one label across the matching series (TS.QUERYLABELS VALUES label [FILTER ...]).
Together with the existing TSQueryIndex they form the drill-down flow
dashboarding tools such as Grafana use to populate variable dropdowns:
label names → values of the chosen label → matching series keys.
Key points shown by the example:
- Filters use the same expression language as
TSQueryIndex/TSMRangeand are passed to the server verbatim; passing no filters queries all indexed series. - Replies are unordered, deduplicated sets of strings; the
LABELSform includes the label names used in the filter itself. - A label carried by no matching series yields an empty reply, not an error.
Prerequisites
Redis 8.10+ with the TimeSeries module, listening on localhost:6379.
Run
go run .
Expected output (order within the collections may differ):
label names for type=sensor: [location type unit]
locations for type=sensor: [bedroom kitchen]
kitchen sensor series: [ts:hum:kitchen ts:temp:kitchen]
values of an absent label: 0
label names, all series: [location type unit]
