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!

Helly guys,
I'm new here, and i would like to clarify some points that i don't really understand so far.
1 - Is Abe a feasible explorer at this date (feb. 01 2018 ) ? How long it takes to load a full database in average?
2 - Where do i find the API containing all the calls and functions from Abe?
3 - Could anyone explain to me what function abe allow to query the bitcoin database?
