Understanding SerDe information when building table in AWS Glue
I'm defining a table in cloudformation which will output to an aws glue data catalog. While I understand most of the resource properites, I don't understand the parts related to SerDe. I'm using this code in my template to help me create a table. 
I'm also having difficulty finding information related to this code as AWS' documentation doesn't explain it very well. At least I'm having difficulty understanding it.
I had the same issue in the past and the solution in my case was to use the documentation for Athena service. Athena service is integrated with Glue Data Catalog. Amazon Athena - SerDe reference
In addition to that Glue Data Catalog is compatible with the Apache Hive metastore, so you can use Apache Hive metastore documentation. In Amazon Athena - SerDe reference, you will also find links to external sources.
I hope this information will be useful to you
