Hi All, I check the documentation of Flink release 1.6, find that I can use checkpoints to resume the program either. As I encountered some problems when using savepoints, I have the following questions: 1. Can I use checkpoints only, but not use savepoints, because it can also use to resume programs. If I do so, is there any problem? 2. Checkpoint can be generated automatically, but savepoints seems can only be generated manually. I have to write a crontab to generate the savepoint, more than this, my Flink program is run on Yarn, and on the machines, only the Hadoop and Yarn are installed, so I can not use flink savepoint command to generate savepoint, and I have no authorization to install Flink on the machines. 3. Will checkpoint and savepoint merged in later releases? Thanks very much. Best, Henry |
