Wow. Really? Is there a way to do micros? A hack? A Jira story? Most (all?) U.S. equity and European futures, options, and stock markets timestamp in microseconds. This makes Flink unusable for a massive industry vertical. To the extent lower-frequency time-series data is being used (e.g. end of data prices), stream processing is kind of overkill. Love everything I've read about Flink...there's got to be a way to make this work, no?
