about the deep clone operation in the cassadra source code

When I read the cassandra code, there are too many deep clone operation. Is there any risk of OutOfMemoryException? When flushing the memtable to disk, there is a deep clone, and when the disk is slow down, this will lead to a severe OOM.

Am I right?

Thanks.

You'll need to be a bit more specific and come up with some steps to reproduce a problem.
