Glue Crawlers don't correctly recognize Ion data - here's how you fix that

Amazon Ion is one of the data serialization formats you can use when exporting data from DynamoDB to S3. Recently, I tried to select data from one of these exports with Athena after using a Glue Crawler to create the schema and table. It didn’t work, and I got a weird error message. In this post, I’ll show you how to fix that problem. If you’re not familiar with Ion yet, check out my recent blog post introducing it for more details.

What is Amazon Ion, and how can I read and write it in Python?

Amazon Ion is a data serialization format that was open-sourced by Amazon in 2016 and is used internally at the company. Over time it has also been introduced into some AWS services and is the data format that services like the Quantum Ledger Database (QLDB) use. It has also started to appear in more commonly used services, so I think it’s worth taking a closer look at. This article will explain what Ion is, its benefits, and how you can use it in Python.
