TL;DR InfluxDB Tech Tips - Creating A Subsample With A Continuous Query

In this weekly post, InfluxDB shares tips on how to create a subsample with a continuous query, workarounds for changing field data types, and answers to frequently asked questions about Continuous Queries and other topics related to InfluxDB. Currently, InfluxDB offers limited support for changing a field's data type, but users can use workarounds such as writing the new data type to a different field or using the shard system. To avoid gaps in data coverage with Continuous Queries, users must increase the `FOR` duration to match the execution interval. Additionally, Continuous Queries require an aggregation function, but users can use selector functions to satisfy this requirement without changing the data.
