Package org.apache.cassandra.schema

Class Indexes

java.lang.Object
org.apache.cassandra.schema.Indexes
All Implemented Interfaces:
Iterable<IndexMetadata>
public final class Indexes extends Object implements Iterable<IndexMetadata>
For backwards compatibility, in the first instance an IndexMetadata must have TargetType.COLUMN and its Set of target columns must contain only a single ColumnIdentifier. Hence, this is what is enforced by the public factory methods on IndexMetadata. These constraints, along with the internal datastructures here will be relaxed as support is added for multiple target columns per-index and for indexes with TargetType.ROW
