+此 Zeta 集群示例使用 16 GB JVM 堆内存。容器内存 request 设置为 20 GiB、limit 设置为 24 GiB，为 
Metaspace、直接内存、线程栈和其他本地内存预留额外空间。对于大规模数据处理场景，建议使用 32 GB JVM 堆内存，并相应提高内存 request 
和 limit，例如分别设置为 36 GiB 和 40 GiB。

+This Zeta cluster example uses a 16 GB JVM heap. Its 20 GiB memory request and 
24 GiB memory limit leave additional container memory for metaspace, direct 
memory, thread stacks, and other native memory. For large-scale data 
processing, a 32 GB JVM heap is recommended; increase the memory request and 
limit accordingly, for example to 36 GiB and 40 GiB.
