Hello Flink Friends! This is a long-shot, but I'm wondering if anyone is thinking or working on applying tracing to Streaming systems and in particular Flink. As far as I understand this is a fairly open problem and so I'm curious how folks are thinking about it and if anyone has considered how they might apply tracing to Flink systems.
Some patterns in Streaming systems fit into tracing fairly easily (consumer fanout-out, for example) but many patterns do not. For example, how do you trace when there is batching or aggregations? Nevertheless, I'm sure some folks have thought about this or even tried to implement solutions, and so I'd love to hear about this. Especially if there are any standards work in this direction (for example, within the OpenTracing project). If you've thought about this, implemented something, or are working on standards related to this, I'd love to hear from you! Thank you! Best, Aaron Levin
