MySQL select request in parallel (python) -


i saw "similar" post executing mysql select * query in parallel, buy question different, , has not been answered either, guess not duplicate.

i trying mysql select request in parallel. reason because need response fast. managed create request when paralleled connection well, connection takes more time actual select faster connect 1 time, , select in parallel.

my approach:

import mysql.connector import multiprocessing  def func(id):     return getfasta(id, cnx).sequence()  cnx = mysql.connector.connect(user='u_name', host='ip_addr', database='db_name') p = multiprocessing.pool()  x in p.imap_unordered(func, ["q32p44", "asd"]):     print x  p.close() p.join() cnx.close()

the getfasta class , working intended, requires connector, , id , simple select those.

if execute script interpreter freezes, , have kill manually. guess either not trivial, or maybe impossible select in parallel 1 connector.

is it?

any workaround?

i found "solution" after lot of research. not possible. mysql not support parallel queries same user. absolutely impossible, , there no plans add this.

the best can way implemented it, parallel connection well.

in other types of databases possible, ll stick mysql , use parallel connection method
