properties - input map

prefix - prefix to choose keys from input map

Returns:

subset of input map with keys starting with provided prefix and prefix trimmed out

filterProperties

public static Map<String,String> filterProperties(Map<String,String> properties,
 Predicate<String> keyPredicate)

Filter the properties map by the provided key predicate.

Parameters:

properties - input map

keyPredicate - predicate to choose keys from input map

Returns:

subset of input map with keys satisfying the predicate

applySchemaChanges

public static Map<String,String> applySchemaChanges(Map<String,String> properties,
 List<String> deletedColumns,
 Map<String,String> renamedColumns,
 Set<String> columnProperties)
