org.apache.hadoop.hbase.client.TableConfiguration

@InterfaceAudience.Private
public class TableConfiguration
extends Object

Configuration is a heavy weight registry that does a lot of string operations and regex matching. Method calls into Configuration account for high CPU usage and have huge performance impact. This class caches the value in the TableConfiguration object to improve performance. see HBASE-12128
