Hi, We are using Flink 1.1.4 version.
There is possibly an issue with EventTimeSessionWindows where a gap is specified for considering items in the same session. Here the logic is, if two adjacent items have a difference in event timestamps of more than the gap then the items are considered to be in separate session. The issue is, what happens if the gap between streaming records is *never* (or for a very long time) less than the session gap. This is likely to lead to a race condition. Is this a bug? How do we deal with this to process windows in finite time? Please could you suggest. Thanks. *Sujit Sakre* Senior Technical Architect Tel: +91 22 6660 6600 Ext: 247 Direct: 6740 5247 Mobile: +91 98672 01204 www.rave-tech.com Follow us on: Twitter <https://twitter.com/Rave_Tech> / LinkedIn <https://in.linkedin.com/in/ravetechnologies> / YouTube <https://www.youtube.com/channel/UCTaO1am-cm4FqnQCGdB6ExA> Rave Technologies – A Northgate Public Services Company <https://www.google.co.in/maps/place/Rave+Technologies/@19.0058078,72.823516,17z/data=!3m1!4b1!4m5!3m4!1s0x3bae17fcde71c3b9:0x1e2a8c0c4a075145!8m2!3d19.0058078!4d72.8257047> Please consider the environment before printing this email -- This email is sent on behalf of Northgate Public Services (UK) Limited and its associated companies including Rave Technologies (India) Pvt Limited (together "Northgate Public Services") and is strictly confidential and intended solely for the addressee(s).
