Thanks you so much for quick resposne. Still the same no difference. (files from one thread goes to folder for another thread)
I checked out the code like below: git clone git fetch origin pull/12/head git checkout 1073eb533fc3478515f4af3a6f779b63c1b651b2 I used Python 3.6. I don't think it is related to Alfresco, I used the same logic for multi-threading using REST API it works just fine.
