I was trying to do the same steps pointed in the original article, but first of all I tried to get the whole database from the blockchain.
I used ABE library to copy the data from bitcoinCore to a SQL database, unfortunately, It take a looooong time to make this job. So, I was wondering if anyone could tell me how to make this job as faster as possible. I'm trying to do this as exercise. I'm new in the bitcoin world, but i'm used to programming in a python and C/C++ throughout my career.
Could anyone explain me the faster way to put the whole blockchain into a database?

Thanks for your time!
