Wordpress Form Submissions

it's so good to have choices . This post is to showcase power of ETL and also to further my knowledge (3 & 4)

I have a simple form on Wordpress which I would like to get into ETL for further processing. Do I 
1. Use URL Logger to get entry via JSON file and then use ETL to process JSON & then create the entry inside MYSQL database
2. Use URL Logger to get entry via JSON file , which then triggers ETL package to mysql database sync from Wordpress mysql to local mysql
3. Somehow use HTTP Monitor to figure a submission has been done (can it know via some trigger ?) , then receive from submission data 
4. Somehow use HTTP Monitor to figure a submission has been done (can it know via some trigger ?) , then trigger ETL package to sync from Wordpress mysql to local mysql
5. Simply put a hourly command to sync all new submissions from Wordpress Mysql to local mysql 

#5 seems easiest if real time data is not required , but I haven't done any update sync yet from ETL , so that should be interesting to figure. 
#3 - #4 HTTP Monitor is alien to me , so team ETL give some feedback
#2 - #1 Easy options , as web hooks are supported natively for form submissions.

HTTP Monitor can be used to trigger AETL package execution but it does not log any data EG URL logger provides more functionality.

Still having options is always good...
