Method Details

createBatchFilter

public static BatchFilter createBatchFilter(Reader.Options opts,
 TypeDescription readSchema,
 boolean isSchemaCaseAware,
 OrcFile.Version version,
 boolean normalize,
 String filePath,
 Configuration conf)

Create a BatchFilter. This considers both the input filter and the SearchArgument filter. If both are available then they are compounded by AND.

Parameters:

opts - for reading the file

readSchema - that should be used

isSchemaCaseAware - identifies if the schema is case-sensitive

version - provides the ORC file version

normalize - identifies if the SArg should be normalized or not

filePath - that is fully qualified to determine plugin filter(s)

conf - configuration shared when determining Plugin filter(s)

Returns:

BatchFilter that represents the SearchArgument or null

createSArgFilter

public static VectorFilter createSArgFilter(org.apache.hadoop.hive.ql.io.sarg.ExpressionTree expr,
 Set<String> colIds,
 List<org.apache.hadoop.hive.ql.io.sarg.PredicateLeaf> leaves,
 TypeDescription readSchema,
 boolean isSchemaCaseAware,
