Re: Composite column/key creation via Hector

[Dave Brosius]

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

Here is something I found in the docs though

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 ?
