I'm using gremlinpython. Inserting a vertex with a property value of greater than 32-bits results in a KeyError.
g.addV('test').property('size', 2147483648).iterate()

KeyError: None
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()
