Subject Re: microsecond resolution
Date Sun, 04 Dec 2016 22:39:54 GMT
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?
