Description:
In flink1.12.0, I saw PartitionTimeExtractor is a constructor without
parameters, why not take the parameter “extractorPattern". See the source code
below:
{code:java}
@Experimental
public interface PartitionTimeExtractor extends Serializable {
String DEFAULT = "default";
String CUSTOM = "custom";
/**
* Extract time from partition keys and values.
*/
LocalDateTime extract(List partitionKeys, List
partitionValues);
static PartitionTimeExtractor create(
ClassLoader userClassLoader,
String extractorKind,
String extractorClass,
String extractorPattern) {
switch (extractorKind) {
case DEFAULT:
return new DefaultPartTimeExtractor(extractorPattern);
case CUSTOM:
try
{ Class aClass = userClassLoader.loadClass(extractorClass); return
(PartitionTimeExtractor) aClass.newInstance(); }
catch (ClassNotFoundException | IllegalAccessException | InstantiationException
e)
{ throw new RuntimeException( "Can not new instance for custom class from " +
extractorClass, e); }
default:
throw new UnsupportedOperationException(
"Unsupported extractor kind: " + extractorKind);
}
}
}
{code}
Would it be more reasonable to bring a parameter construction method? as
follows:
try
{ Class aClass = userClassLoader.loadClass(extractorClass); Constructor
declaredConstructor = aClass.getDeclaredConstructor(String.class);
return (PartitionTimeExtractor)
declaredConstructor.newInstance(extractorPattern); }
catch (ClassNotFoundException | IllegalAccessException | InstantiationException
| NoSuchMethodException | InvocationTargetException e)
{ throw new RuntimeException( "Can not new instance for custom class from " +
extractorClass, e); }

Summary: Improvements in custom partition extractor
Key: FLINK-20936
URL: https://issues.apache.org/jira/browse/FLINK-20936
Project: Flink
Issue Type: Improvement
Components: Connectors / Hive
Affects Versions: 1.12.0
Environment: flink 1.12.0
jdk 1.8
Reporter: zhoukui
In flink1.12.0, I saw PartitionTimeExtractor is a constructor without
parameters, why not take the parameter “extractorPattern". See the source code
below:
@Experimental
public interface PartitionTimeExtractor extends Serializable {
String DEFAULT = "default";
String CUSTOM = "custom";
/**

LocalDateTime extract(List partitionKeys, List
partitionValues);
static PartitionTimeExtractor create(
ClassLoader userClassLoader,
String extractorKind,
String extractorClass,
String extractorPattern) {
switch (extractorKind) {
case DEFAULT:
return new DefaultPartTimeExtractor(extractorPattern);
case CUSTOM:
try {
Class aClass = userClassLoader.loadClass(extractorClass);
return (PartitionTimeExtractor) aClass.newInstance();
} catch (ClassNotFoundException | IllegalAccessException |
InstantiationException e) {
throw new RuntimeException(
"Can not new instance for custom class from " + extractorClass, e);
}
default:
throw new UnsupportedOperationException(
"Unsupported extractor kind: " + extractorKind);
}
}
}
Would it be more reasonable to bring a construction method? as follows:

return (PartitionTimeExtractor)
declaredConstructor.newInstance(extractorPattern);
