Package org.apache.cassandra.index.sai.view

Class View

java.lang.Object

org.apache.cassandra.index.sai.view.View

All Implemented Interfaces:

Iterable<SSTableIndex>

public class View
extends Object
implements Iterable<SSTableIndex>

The View is an immutable, point in time, view of the avalailable SSTableIndexes for an index.

The view maintains a RangeTermTree for querying the view by value range. This is used by the QueryViewBuilder to select the set of SSTableIndexes to perform a query without needing to query indexes that are known not to contain to the requested expression value range.
