Re: [DISCUSS] Table API / SQL internal timestamp handling

Hi Shaoxuan, I really appreciate your prompt reply. What you explained makes sense to me. There is only one point that I got some different ideas about "we have to buffer all the delta data between watermarks of two inputs". Consider the following SQL on joining two streams l and r: SELECT *

Re: Class Cache

Hey Mike! Thanks for the detailed information about your setup. I'm also puzzled by this... (1) Which version of Flink are you using? We recently merged some changes to the JAR distribution components, which might cause this (although I think that's unlikely). (2) As a temporary work around you

Re: Class Cache

Hi Mike! Flink does in fact cache jar files in the "blob server". But these are cached subject to the following conditions: - No caching across "sessions", meaning start/stop of the cluster/jobmanager. If you run the per-job-yarn setup, the job does not cache anything. - Files are cached

Re: Class Cache

No, I did not explicitly create an uber-jar. The mylib1.jar is very light. It only contains my main application class (including ProcessFunction). I have been specifying --classpath option on my flink run command to pull in the mylib2.jar . Plus, I have been rebuilding mylib1.jar

Re: Class Cache

A Flink program is typically packaged as an 'uber-jar' containing its dependencies. The Flink quickstart project illustrates this (see the use of the shading plugin in pom.xml). Based on your description, the classes of mylib2.jar were copied into mylib1.jar when the latter was built. Try

Are classes cached somewhere in flink? I am running in a very basic, local environment on Linux (start_local.sh). I've somehow gotten my environment into a strange state that I don't understand. I feel like I am overlooking something simple, but I've checked everything I can think of. My

Hi Jark, yes, the handling of watermarks is very tricky. It is not directly related to the proposal which is only about the representation of timestamps but becomes important for event-time joins. We have a JIRA about an operator that is able to hold back watermarks [1]. Roughly the idea is to
