@sticnarf @ekexium @MyonKeminta @cfzjywxk . thanks for your review ! |

Maybe we need to verify the performance impact of cloning the stats. |
|
I think just copying the pointer is enough as the underlying data would not change, the price is it's not real clone. |

SnapshotRuntimeStatsto slow log, but we found that the TimeDetail and 'ScanDetail' is lost. It is because that Cloning SnapshotRuntimeStats omits some information.
