## Summary of Changes
Hello @tqchen, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull
request and will post my feedback shortly. In the meantime, here's a summary to
help you and other reviewers quickly get up to speed!
This pull request optimizes the `JSONGraphNode` class by implementing a
caching mechanism for shape and data type information. By storing these
frequently accessed properties directly as member variables, the system reduces
redundant attribute parsing, thereby improving the overall performance and
efficiency of JSON graph operations.
### Highlights
* **Performance Improvement**: Introduced caching for shape and dtype arrays
within the `JSONGraphNode` class to enhance efficiency during JSON graph access.
* **Class Structure Update**: Added new member variables `shape_` (for
`ffi::Array>`) and `dtype_` (for `ffi::Array`)
to `JSONGraphNode` to store cached values.
* **Constructor Modification**: Updated the `JSONGraphNode` constructor to
populate the newly introduced `shape_` and `dtype_` member variables from
existing attributes upon object creation.
* **Accessor Optimization**: Modified `GetOpShape()` and `GetOpDataType()`
methods to directly return the cached `shape_` and `dtype_` values, eliminating
the need for repeated attribute lookups.
* **Setter Integration**: Adjusted `SetShape()` and `SetDType()` methods to
not only set the attributes but also update the corresponding cached `shape_`
and `dtype_` member variables.
🧠**New Feature in Public Preview:** You can now enable **Memory** to help
**Gemini Code Assist** learn from your team's feedback. This makes future code
reviews more consistent and personalized to your project's style. **Click

admin console.**
Changelog
* **src/runtime/contrib/json/json_node.h**
* Added `shape_` and `dtype_` member variables to `JSONGraphNode` for
caching.
* Modified the `JSONGraphNode` constructor to initialize `shape_` and
`dtype_` from existing attributes.
* Updated `GetOpShape()` and `GetOpDataType()` to return the cached
`shape_` and `dtype_` respectively.
* Adjusted `SetShape()` and `SetDType()` to also update the new cached
member variables.
