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.

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.
