InfluxDB is a time-series database that allows developers to automatically downsample data from one measurement and save those downsampled data in another measurement using continuous queries or raw INTO queries. However, the syntax for continuous queries can be tricky, and including a `WHERE` clause with a time range won't work as expected. Instead, developers should use basic raw INTO queries that accept a time range in the `WHERE` clause to achieve this functionality. Additionally, InfluxDB's Line Protocol only accepts epoch timestamps, but developers can specify an alternative timestamp precision using query string parameters.
