将DSE cassandra迁移到Apache cassandra-JVM设置

Question

当前，我们正在使用DSE 6.0.4版本，并计划迁移到Apache cassandra 3.11.6。使用apache cassandra创建了一个全新的集群，当我比较Apache VS DSE之间的JVM设置（jvm.options）时，我发现DSE具有更多设置。

例如：-

以下设置存在于DSE版本中，但在apache cassandra中不存在。是否可以在apache cassandra JVM.options文件中添加这些参数？还是不需要？

# Align direct memory allocations
-Dsun.nio.PageAlignDirectMemory=true

# Honor user code @Contended annotations
-XX:-RestrictContended

# Decrease frequency of guaranteed safepoints to avoid needless pauses
-XX:+UnlockDiagnosticVMOptions
-XX:GuaranteedSafepointInterval=300000

# There's no adverse side effect to enabling the debug info, so leave on by default to allow better info for profilers
-XX:+UnlockDiagnosticVMOptions
-XX:+DebugNonSafepoints
