Call Sequence of Spring Boot when API call is invoked.

 Please note that this is incomplete and not accurate, and I'm merely jotting down anything that I've found out, as I'm short on time while writing this.

When the API is called, the call sequence within the spring boot library is shown below:

In the org.springframework:spring.webmvc library, specifically in the RequestMappingHandlerAdapter class, the call sequence: 

1) handleInternal method, it will check session. 

2) invokeHandlerMethod that I think it will handle the passing of parameter. (Note that this is just an assumption) 

3) getDataBinderFactory method, which i think will handle the binding of the value from the parameter into the endpoints parameter request. 

4)  createInitBinderMethod method, which i think will make the parameter discoverable.

 5) getModelFactory method, which I think will get the list of endpoints registered

6) getSessionAttributesHandler, which handles the cases when session is found or not

7) createInvocableHandlerMethod, which handles the endpoint to be callable.

Then, the endpoint is then called.

Running CQL scripts in Cassandra

How to run CQL scripts in Cassandra  There are 2 ways to run a CQL script, the first way would be running the following command: - cqlsh -f {directory} The second way would be using the command within the CQLSH terminal: - source '{directory}' Where does the {directory} points to? The directory points to the root of your server. For example, if you are on linux, the root would be `/`. Therefore, if you placed your scripts under the folder `scripts`, your directory would look like this `/scripts/{cql_script_name}.cql`.  I've been running the command, but it keeps saying `No such file or directory`? If you met this error, please make sure that:      - The file actually exist in the directory. You can check if by typing `ls -l {directory}`. If it doesn't exist, it will show the same error. If you are on docker, and you are unsure of how to mount your CQL file into your container, you can check out this guide.      - The CQL file has the correct exten...
