kyoty opened a new pull request #32313:
URL: https://github.com/apache/spark/pull/32313
### What changes were proposed in this pull request?
SImply the `getOperationType ` method.
Introduce a `HashMap` to cache the existed enumeration types, so as to avoid
a linear search in a for loop.
### Why are the changes needed?
`OperationType.getOperationType` can be called in
OperationHandler.constructor:
```java
public OperationHandle(TOperationHandle tOperationHandle, TProtocolVersion
protocol) {
super(tOperationHandle.getOperationId());
this.opType =
OperationType.getOperationType(tOperationHandle.getOperationType());
this.hasResultSet = tOperationHandle.isHasResultSet();
this.protocol = protocol;
}
```
`OperationHandle ` is widely used, It's better to improve the execution
efficiency of `OperationType.getOperationType`
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Just a refractor, using Existing UTs
