QUESTION
I have a script to migrate database from Sqlite to Postgres. My original scipt works, but when I try to use Asyncio to speed up program, my new code even running slower than the original a few seconds. The transfer speed of tables is very slow. Can anyone suggest to me, where am I wrong ?
My original code :
...ANSWER
Answered 2020-Feb-02 at 00:48If both databases located on a same computer, asyncio
won't speedup a process: there's no network overhead to parallelize. Quite opposite: overhead for using coroutines will make program a bit slower.
Please, read this answer for detailed explanation.
QUESTION
I have a script used to migrate data from SQLite to Postgres. I just use a for loop to transfer tables one by one. Now, I want to experiment with transfering multiple tables in concurrency using threads, multiprocessing or asyncio to speed up the program to compare the runtimes between those ways. How do you do one of those ways?
Here is my script:

into a function, say copyTable
. Then you're able to use the multiprocessing
package to parallelize your code. It should look something like this:
