Hi @davehowell,
It seems it was an oversight in a blog post. Latest Spark Enrich version is indeed 1.19.0 and latest AMI is 5.9.0. We’ll fix this in the blog post.
However, since you mentioned you’re planning to move to the streaming architecture, I just wanted to raise that Spark Enrich is a part of batch architecture and already deprecated in R118. In streaming architecture on AWS, Stream Enrich is responsible for enrichment and RDB Shredder is the last component that requires EMR. You can have a look at this post that highlights differences and provides step-by-step migration guide.
