This document presents RedisTimeSeries, which provides time series functionality for Redis. It defines a time series as a series of data points indexed in time order. RedisTimeSeries allows ingesting, querying, aggregating, and downsampling of time series data stored in Redis in a more optimized way than traditional Redis methods. It provides features like labeling of time series for enhanced queries, aggregation functions, and integration with tools like Prometheus and Grafana. The presentation includes demos of using RedisTimeSeries to store and analyze weather station and web page view count data.
