Class BTree.FastBuilder<V>

java.lang.Object

org.apache.cassandra.utils.btree.BTree.FastBuilder<V>

All Implemented Interfaces:

java.lang.AutoCloseable

Enclosing class:

BTree

public static class BTree.FastBuilder<V>
extends java.lang.Object
implements java.lang.AutoCloseable

A pooled builder for constructing a tree in-order, and without needing any reconciliation.

Constructs whole nodes in place, so that a flush of a complete node can take its buffer entirely. Since we build trees of a predictable shape (i.e. perfectly dense) we do not construct a size map.
