Re: Composite column/key creation via Hector

BTW, an issue was just fixed with dynamic columns in hector, you might 
want to try trunk.

Hi all,

What is the right way to create CF with dynamic composite column and 
composite key?


Now I use code like this:

 private static final String DEFAULT_DYNAMIC_COMPOSITE_ALIAES =

"(a=>AsciiType,b=>BytesType,i=>IntegerType,x=>LexicalUUIDType,l=>LongType,t=>TimeUUIDType,s=>UTF8Type,u=>UUIDType,A=>AsciiType(reversed=true),B=>BytesType(reversed=true),I=>IntegerType(reversed=true),X=>LexicalUUIDType(reversed=true),L=>LongType(reversed=true),T=>TimeUUIDType(reversed=true),S=>UTF8Type(reversed=true),U=>UUIDType(reversed=true))";


for composite columns:
 BasicColumnFamilyDefinition columnFamilyDefinition = new 
BasicColumnFamilyDefinition();
columnFamilyDefinition.setComparatorType( 
ComparatorType.DYNAMICCOMPOSITETYPE );
columnFamilyDefinition.setComparatorTypeAlias( 
DEFAULT_DYNAMIC_COMPOSITE_ALIAES );

columnFamilyDefinition.setKeyspaceName( keyspaceName );
columnFamilyDefinition.setName( "TestCase" );
columnFamilyDefinition.setColumnType( ColumnType.STANDARD );
ColumnFamilyDefinition cfDefStandard = new ThriftCfDef( 
columnFamilyDefinition );
cfDefStandard.setKeyValidationClass( 
ComparatorType.UTF8TYPE.getClassName() );
cfDefStandard.setDefaultValidationClass( 
ComparatorType.UTF8TYPE.getClassName() );


for keys:
columnFamilyDefinition = new BasicColumnFamilyDefinition();
columnFamilyDefinition.setComparatorType( 
ComparatorType.UTF8TYPE );

columnFamilyDefinition.setKeyspaceName( keyspaceName );
columnFamilyDefinition.setName( "Parameter" );
columnFamilyDefinition.setColumnType( ColumnType.STANDARD );
cfDefStandard = new ThriftCfDef( columnFamilyDefinition );
cfDefStandard.setKeyValidationClass( 
ComparatorType.DYNAMICCOMPOSITETYPE.getClassName() + 
DEFAULT_DYNAMIC_COMPOSITE_ALIAES );
cfDefStandard.setDefaultValidationClass( 
ComparatorType.UTF8TYPE.getClassName() );


Does it correct code? Do I really need 
so terrible DEFAULT_DYNAMIC_COMPOSITE_ALIAES ?
