Bitbucket and Jira events to kafka

[Ramkumar]

We have requirement to push all bitbucket and Jira events to kafka. In marketplace we observed there is no built in plugin already available to do this. Custom approach can be push model using webhook or pull model using cron jobs but each has it owns pro and cons.
with push if the listening endpoint is down then event can get lost. With pull model with increasing number of project/repo its there can be a latency to query each repo and also wont be real time.
Are there any S3 sink connector available to push all the events to S3 ?

And what are the other possible options atlassian products(Bitbucket ,Jira) support ?
