InfluxDB Cloud 3.0 is a versatile time series database built on top of the Apache ecosystem, allowing users to query it with the Apache Arrow Flight SQL interface for efficient working with time series data. A tutorial guides users through querying InfluxDB Cloud using the Go Flight SQL Client, which provides high-performance data services and efficiently transmits large datasets over gRPC. The tutorial assumes a free InfluxDB Cloud account and Docker setup, requiring authentication environment variables such as a token and organization to be set up before executing queries on the server. With this guide, users can explore querying InfluxDB Cloud with Flight SQL for their own projects, taking advantage of features like downsampling and data processing with tools of their choice.
