I ran across a kind of fun problem today that I wanted to run past you Gentle
Geniuses (tm):
- Imagine an environment in which there may be multiple instances of a given
microservice written in Python.
- Each of these services needs to produce a string of ten digits guaranteed to
be unique
on a per service instance basis AND to not collide for - oh, let's say -
forever :)s
Can anyone suggest a randomization method that might achieve this efficiently?
My first thought was to something like nanonseconds since the epoch plus
something
unique about the service instance - like it's IP? (This is in a K8s cluster) -
to
see the randomization and essentially eliminate the string being repeated.
Ideas welcome ..
P.S. I do not want to resort to a number generation service that each instance
asks
for a new number. The network and service call overhead militates against
this
in my application.
