AWS Glue - setting data target for RDS mysql

Question

I've started using Glue and I'm having trouble understanding how the data targets work.
Using visual method to create a new Job I selected target to be MySQL (that is where I want the data to be saved). In the next tab, Data target properties, I can only select the Database from the Glue's data catalog and not from the target db.
Are there any pre-requisites I need to complete before I can save the table in AWS RDS mysql?

Answer

AWS Glue studio has the[ following three options for target properties](https://docs.aws.amazon.com/glue/latest/ug/data-target-nodes.html). It can write to,
* S3
* AWS Glue Data Catalog 
* A connector

In this case, you might want to catalog the target database in the Glue data catalog before trying to read it from the data target properties. This means [crawling the target database, and storing the metadata in Glue's data catalog](https://docs.aws.amazon.com/glue/latest/dg/populate-data-catalog.html), by which way we can map this information to the AWS RDS MySQL target.
