python - Parallel calls to CouchDB -


i'd stress test clouddb cluster python3 can't multithreading work properly. have used google , there many ways this, of them way complicated me and/or use case.

what try save document couchdb on 3 nodes @ same time. how use simple way of multithreading possible this?

import couchdb import random import time import _thread  servers = {     "pizerogrijs": "http://admin:admin@pizerogrijs.local:5984/",     "pizerogeel": "http://admin:admin@pizerogeel.local:5984/",     "pizeroroze": "http://admin:admin@pizeroroze.local:5984/" }  databasename = 'testhijs'  class bank(object):     def __init__(self):         self.dbs = {}         s in servers:                 self.dbs[s] = couchdb.server(servers[s])[databasename]      def showdbs(self):         print(self.dbs)      def randomwrite(self, data):         randomdb = self.dbs[random.choice(list(self.dbs))]         return(randomdb.save(data))      def directwrite(self, server, data):         start = time.time()         directdb = self.dbs[server]         end = time.time()         print(directdb.save(data))         print(end - start)  def streskip(server):     db.directwrite(server, {"test": "thijs"})  db = bank()  _thread.start_new_thread(streskip('pizerogrijs'), ()) _thread.start_new_thread(streskip('pizerogeel'), ()) _thread.start_new_thread(streskip('pizeroroze'), ())  while 1:    pass

the response is:

/usr/bin/python3.6 /home/thijs/repos/databos/test.py ('f4e66074fdae56c6de6b1d744033eb63', '1-a8238505469902134486a6744284a43a') 9.5367431640625e-07 traceback (most recent call last):   file "/home/thijs/repos/databos/test.py", line 39, in <module>     _thread.start_new_thread(streskip('pizerogrijs'), ()) typeerror: first arg must callable  process finished exit code 1

i needed add arguments in tuple , not directly. so.

_thread.start_new_thread(streskip, ('pizerogrijs',)) _thread.start_new_thread(streskip, ('pizerogeel',)) _thread.start_new_thread(streskip, ('pizeroroze',))

the rest of code fine , simple way of multi threading find.
