mysql - What's faster/more efficient: Continuous Deleting OR Continuous Updating + Intermittent Deleting? -

-

I have a cron that runs through several rows, removal of "bad" people (as per my criteria) . I'm wondering what would be best to optimize the script. I can do one of the following:

  1. Remove the "bad" rows immediately after finding the same cron.

  2. Update the same cron immediately as the "bad" rows as "1", which means bad. Again, I can set another chronometer which runs and eliminates all the rows with an "1" status for an hour. To make it fast, I think I have an index on "status", but it can also ruin the display.

Any suggestions?

I have not experienced in my SSQL but on other DBMS I have worked on an update and then Removes no help Just try and remove with huge amounts of data, measure the time when the update + is removed, it helps if there is an index of the columns that act as the criteria of "bad" people.

Obfuscating Python code? -

-
I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
