   > Thanks @hy00nc! I've left some comments. I also have two questions regarding the issue
description.
   > 
   > First, I was not able to find in the code "If there is any chance of using getData()
in SerializedPartition, we check the length of the SerializedData to ensure that this SerializedPartition
was created from existing data". Can you point me to it?
   > 
   > Second, can you file a JIRA issue and add a TODO comment besides `allocateDirect`?
That would make it clear that line of code causes overheads.
   > 
   > e.g.,
   > // TODO #999: ISSUE_TITLE
   
   Thanks for the review @johnyangk !
   
   For the first question, I didn't update the comment after addressing some fixes for the
bug. Sorry for the confusion. Please check the updated comment :)
   
   For the second one, maybe I can add to the existing [JIRA](https://issues.apache.org/jira/projects/NEMO/issues/NEMO-388)
about the overhead. I will also add the TODO in the code, thanks!
