I think i got the answer.
issue was with python 3.8 & Tornado compatibility, when it comes to asyncio.
more info is at this link
fix was to add following line in tornado/platform/asyncio.py
asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy()) # python-3.8.0a4

A value of less than 32 bits works fine
g.addV('test').property('size', 2147483647).iterate()
Casting it to float also works fine
g.addV('test').property('size', float(2147483648)).iterate()
Same behavior with a locally running gremlin server and a remote Neptune DB. It works fine from the gremlin console. So I don't think this is a server issue.
Python version - 3.6 and 3.7
gremlinpython version - 3.4.1
You explicitly need to define that number as a long() like:
from gremlin_python.statics import *
g.addV('test').property('size', long(2147483648)).iterate()

What's wrong with MySQL ? Could someone give me some advice ?
make sure mysql service is running using
service mysql status
next make sure it is listening on "10.0.3.139".
By default mysql listens on localhost.
To change that edit /etc/mysql/my.cnf and set the bind-address to 0.0.0.0 and restart the service. This will make it to listen on all the available interfaces.
Finally you have to make sure the mysql database, user and password are configured properly in /etc/keystone/keystone.conf and also that the user/database are created in mysql.
Use the below link for more details.
