-----------------------------------
Summary: Simplify operationType.getOperationType by using a
hashMap.
Key: SPARK-35205
URL: https://issues.apache.org/jira/browse/SPARK-35205
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.0.1
Reporter: akiyamaneko
SImply the *getOperationType* method.
Introduce a *HashMap* to cache the existed enumeration types, so as to avoid a
linear search in a for loop.
`*OperationType.getOperationType*` can be called in
OperationHandler.constructor:
{code:java}
public OperationHandle(TOperationHandle tOperationHandle, TProtocolVersion
protocol) {
super(tOperationHandle.getOperationId());
this.opType =
OperationType.getOperationType(tOperationHandle.getOperationType());
this.hasResultSet = tOperationHandle.isHasResultSet();
this.protocol = protocol;
}
{code}
`*OperationHandle* ` is widely used, It's better to improve the execution
efficiency of `OperationType.getOperationType`
