TimescaleDB provides a number of time-oriented functions that improve ease of use for time-series analytics and performance, reducing the learning curve for developers who already know SQL. Two critical functions are time_bucket() and time_bucket_gapfill(), which enable aggregating arbitrarily-sized time periods and filling gaps in time buckets with either locf() or interpolate(). These functions allow users to write simpler queries and visualize data more effectively, making them essential for analyzing and visualizing time series data. TimescaleDB has been offering these functions since its first release in April 2017, and they are particularly useful when graphing time-series data using solutions like Grafana.
