I am trying to run flink on kubernetes, and trying to push checkpoints to Google Cloud Storage. Below is the docker file
`FROM flink:1.6.2-hadoop28-scala_2.11-alpine RUN wget -O lib/gcs-connector-latest-hadoop2.jar https://storage.googleapis.com/hadoop-lib/gcs/gcs-connector-latest-hadoop2.jar RUN wget -O lib/gcs-connector-latest-hadoop2.jar https://storage.googleapis.com/hadoop-lib/gcs/gcs-connector-latest-hadoop2.jar && \ wget http://ftp.fau.de/apache/flink/flink-1.6.2/flink-1.6.2-bin-hadoop28-scala_2.11.tgz && \ tar xf flink-1.6.2-bin-hadoop28-scala_2.11.tgz && \ mv flink-1.6.2/lib/flink-shaded-hadoop2* lib/ && \ rm -r flink-1.6.2*` But the checkpoints are taking around 2-3 seconds on average and around 25 seconds at max, even the state size is around 100 KB. Even the jobs are getting restarted with the error `AsynchronousException{java.lang.Exception: Could not materialize checkpoint 1640 for operator groupBy` and sometimes losing connections with task managers. Currently, I have given the heap size of 4096 MB. -- Sent from: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/
