Graceful Shutdown of Workers #42

Open cbatson opened 3 years ago

cbatson commented 3 years ago

Similar to https://github.com/awslabs/amazon-kinesis-client-nodejs/issues/34

Would like to see this functionality in the Ruby client for MultiLangDaemon.

Thank you.

@pfifer shutdown doesn't work at all. https://github.com/awslabs/amazon-kinesis-client/pull/174 its easily reproducible with the given samples as well. Just start it up, hit control+c, nothing ever gracefully exits it just spews errors and blows up.

The ioproxy class is getting the signal propagated to it, it feels like signal handling needs to be caught by the java process and not sent down to the child process until after the shutdown initiate has occurred.
