> When I'm trying to upgrade Samza to 0.13 (from 0.11), I got the error below when trying to start our job:

> Looking at Samza code on Github, it seems Samza just started to restrict topic names to a stricter sets. It doesn't allow '.' anymore whereas we have been using '.' for all of our topics. That means we cannot upgrade to Samza 0.13 without changing all the topics. That also breaks our convention for defining topic names. Having '.' in the topic name is actually very convenient for us because they can be shown in Grafana/StatsD in a more organized way.
> Here is the change in Github: https://github.com/apache/samza/commit/e6c1eed4f1d576661abafce8477c1749c2554b39#diff-98a114809fb1ab416f8d1d0b4d318b96R201
> Can you expand the regex set to a larger set including '.'? Thanks in advance!
