ConnectionConfiguration (Apache HBase

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

```
@InterfaceAudience.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
