Apache Infra GitHub Event Notification Service
This service runs in the background and pulls in GitHub activity from our pubsub service. new/closed/merged issues/prs and code/issue comments are emailed to the appropriate mailing list. Where a code review from a user contains several comments on different pieces of code, the comments are collated into a single email.
The plan is to also add JIRA support later, for adding links and labels to JIRA tickets.
