The V2 Data Engine is an experimental feature and should not be used in production environments. **Caution**: [1] **Do not modify this setting while volumes are still attached.** [2] When the V2 Data Engine is enabled, each Instance Manager pod for the V2 Data Engine uses 1 CPU core. The high CPU usage is caused by `spdk_tgt`, a process running in each Instance Manager pod that handles input/output (IO) operations and requires intensive polling. `spdk_tgt` consumes 100% of a dedicated CPU core to efficiently manage and process the IO requests, ensuring optimal performance and responsiveness for storage operations."
