I have 11 big files (text file with raw data) on the FTP server.

And also have another source on Google Big Query (11 tables).



And I need to build a process to compare 2 sources (the data in FTP and GBQ) to find out the new records (this process need to run as daily, the FTP server will update files every morning). And this is the path I used:




  • I export all the data ( 11 tables) on GBQ and download it to my local, and create historical data by MySQL.

  • After that, I read the data in the FTP server and compare with historical data to find out the new records (use a simple query).

  • Send it to GBQ, also insert to historical data.


Is this way is the best solution? Could anyone please can recommend me another solution?

          Refactoring coordinates for Minecraft Pi buildings written in Python

          0 $begingroup$ I'm fairly new to coding and I wrote this script in Python for a house with a roof in Minecraft Pi. I've found different ways to write the coordinates to make the code base shorter, but I'm wondering if it is possible for me to refactor it any further so I don't have to list each coordinate line by line. import mcpi.minecraft as minecraft import mcpi.block as block mc = minecraft.Minecraft.create() p = mc.player.getTilePos() mc.setBlocks(p.x+1, p.y, p.z+1, #Main structure starting coordinates (DO NOT ALTER) p.x+19, p.y+4, p.z+6, #Structure size/coordinates (Alters cube size) block.STONE_BRICK) mc.setBlocks(p.x+2, p.y+1, p.z+2, #Hollowing out main structure interior p.x+18, p.y+3, p.z+5, block.AIR) mc.setBlocks(p.x, p.y...
