Add support for multiple aggregators in TS.RANGE, TS.REVRANGE, TS.MRANGE, and TS.MREVRANGE
This PR adds support for passing multiple aggregators to the TimeSeries
range,revrange,mrange, andmrevrangecommands, as introduced in Redis 8.8.Previously, these commands only accepted a single
aggregation_typeparameter.With this change, users can now pass a list of aggregation types (e.g.,
["avg", "max"]) to retrieve multiple aggregations in a single call.The existing single-aggregator usage remains fully backward compatible.
Both the sync and async implementations have been updated to ensure full parity.
The
aggregation_typeparameter now accepts either a single string or a list of strings, and the command construction logic correctly serializes multiple aggregators when a list is provided.No public API signatures were broken — existing callers passing a single string will continue to work without any changes.
New tests have been added for both sync (
test_timeseries.py) and async (test_asyncio/test_timeseries.py) covering multi-aggregator scenarios forrange,revrange,mrange, andmrevrange.Note
Medium Risk
Extends
TS.RANGE/TS.MRANGEfamily to accept list-based aggregations and changes parsing to return variable-width samples, which may affect callers that assume a fixed[timestamp, value]shape when opting into the new feature.Overview
Adds RedisTimeSeries multi-aggregator support by allowing
aggregation_typeto be alist[str]inTS.RANGE,TS.REVRANGE,TS.MRANGE, andTS.MREVRANGE, serializing lists as a comma-separatedAGGREGATIONargument.Updates response parsing so range samples can contain multiple float values per timestamp, and introduces validation that forbids
GROUPBYwhen more than one aggregator is specified. Sync and asyncio test suites add coverage for multi-aggregator queries and theGROUPBYerror case.Reviewed by Cursor Bugbot for commit e93d536. Bugbot is set up for automated code reviews on this repo. Configure here.
