Hi all, I have some questions about the experience I had with the save point. So, last night I found my flink cluster's memory usage seemed wired, so I decided to
1. create a savepoint for the running job(there was only one job running at the time) 2. and then cancel the job from web UI 3. and restart the cluster and when I tried to resume the job with the savepoint, there was a "Truncate did not truncate to right length. Should be 11757 is 56383." exception. Because there is also a savepoint being created every 4 a.m. in the morning, so after I failed to run the job with the savepoint I created before I canceled the job, I tried to use the 4 a.m. savepoint instead, and it seemed to work well. Then this morning, I noticed there is data lost for the time after I cancel the job and before I resume the job. I thought if I run the job with savepoint created in 4 a.m., it should start to process data from 4 a.m., or I'm missing something here? Also, I didn't add uid to the addSource() function, maybe when I restarted the cluster the auto-generated id has been changed and that might be the reason why the recovery didn't go well?
