Class ConnectionConfiguration

java.lang.Object
org.apache.hadoop.hbase.client.ConnectionConfiguration

@Private public class ConnectionConfiguration extends Object
Configuration parameters for the connection. 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 connection-related configuration values in the ConnectionConfiguration object so that expensive conf.getXXX() calls are avoided every time HTable, etc is instantiated. see HBASE-12128
