What is Karate DSL?

Combines API test-automation, mocks and performance-testing into a single, unified framework. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. Besides powerful JSON & XML assertions, you can run tests in parallel for speed - which is critical for HTTP API testing.
Karate DSL is a tool in the Testing Frameworks category of a tech stack.
Karate DSL is an open source tool with 4.5K GitHub stars and 1.1K GitHub forks. Here’s a link to Karate DSL's open source repository on GitHub

I want to develop a custom API testing tool for which I have chosen Karate DSL. As I will be dealing with APIs, I need to handle lots of data in JSON or XML format. I need advice on which DB is best suited for my application. MongoDB or MySQL?

Please Suggest. Thank you in advance.
