Hi, I'm trying to implement the partition keys and filter methods of the LoadMetadata interface for the HiveColumnarLoader function. But have one question as to how would I use the Expression parameter in the setPartitionFilter(Expression) method.
I know this contains the filter expressions that are applied against partition keys in my Loader, but is there an 'Executor' or class that evaluates this expression? I was thinking of using some kind of EL library but wanted to make sure I'm not re-implementing something that is already there. Thanks, Gerrit
