Brandon Williams updated CASSANDRA-3280:
----------------------------------------
Labels: (was: patch)
> Pig Storage Handler: Add >=0.8.1 types, Guess right type for Key in Schema
> --------------------------------------------------------------------------
>
> Key: CASSANDRA-3280
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3280
> Project: Cassandra
> Issue Type: Improvement
> Components: Hadoop
> Affects Versions: 0.8.1
> Reporter: Steeve Morin
> Fix For: 0.8.8, 1.0.1
>
> Attachments: new_types_and_key_type.txt, new_types_and_key_type_v2.txt
>
>
> Various patches in the Pig Storage Handler:
> - correctly guess the right Pig type for the Row Key
> - add support for FloatType, DoubleType, -UUIDType (as String) and DateType
> (as time epoch)- (removed in v2 because it would break when storing data back
> in Cassandra)
> - add support to specify correct type comparator in SlicePredicate
> *SlicePredicate comparator:*
> For instance:
> {quote}
> {{raw = LOAD
> 'cassandra://ks/cf?slice_start=2.5&slice_end=5.3&comparator=DoubleType' USING
> CassandraStorage() AS ();}}
> {quote}
> It's an optional parameter. If it's not present, it will default to
> BytesType. Which mean you must use hex strings.
> Hence {{slice_start=00&slice_end=FF}} isn't the same as
> {{slice_start=00&slice_end=FF&comparator=AsciiType}} !
