TL;DR InfluxDB Tech Tips: Downsampling with Flight SQL and AWS Lambda

This tutorial demonstrates how to perform downsampling with InfluxDB IOx, a new storage engine for InfluxDB Cloud, using AWS Lambda. It covers importing dependencies, gathering authentication credentials, instantiating the Flight SQL client, executing a query, creating a reader object, reading data into a pyarrow.Table object, converting data to a Pandas DataFrame, and writing the data back to InfluxDB. Additionally, it provides instructions on creating an AWS Lambda function, deploying the script, and running the Lambda function on a schedule using CloudWatch or EventBridge. InfluxDB IOx addresses key user needs, including unlimited cardinality, SQL support, and fast analytics, by leveraging Apache ecosystem technologies such as Parquet, DataFusion, Arrow, and Flight SQL.
