  - getSocketBufferSizeHints
```
public int[] getSocketBufferSizeHints()
```
    Returns the optional size hints (in bytes) for the low level TCP send and receive buffers. This is an advanced option for advanced users who want to tune low level TCP parameters to try and squeeze out more performance.
    The optimal TCP buffer sizes for a particular application are highly dependent on network configuration and operating system configuration and capabilities. For example, most modern operating systems provide auto-tuning functionality for TCP buffer sizes, which can have a big impact on performance for TCP connections that are held open long enough for the auto-tuning to optimize buffer sizes.
    Large buffer sizes (ex: 2MB) will allow the operating system to buffer more data in memory without requiring the remote server to acknowledge receipt of that information, so can be particularly useful when the network has high latency.
    This is only a hint, and the operating system may choose not to honor it. When using this option, users should always check the operating system's configured limits and defaults. Most OS's have a maximum TCP buffer size limit configured, and won't let you go beyond that limit unless you explicitly raise the max TCP buffer size limit.
    There are many resources available online to help with configuring TCP buffer sizes and operating system specific TCP settings, including:
    - http://onlamp.com/pub/a/onlamp/2005/11/17/tcp_tuning.html
    - http://fasterdata.es.net/TCP-tuning/
    Returns:
    A two element array containing first the TCP send buffer size hint and then the TCP receive buffer size hint.

  - getSignerOverride
```
public String getSignerOverride()
```
    Returns the name of the signature algorithm to use for signing requests made by this client. If not set or explicitly set to null, the client will choose a signature algorithm to use based on a configuration file of supported signature algorithms for the service and region.
    Most users do not need to concern themselves with which signature algorithm is being used, as the defaults will be sufficient. This setting exists only so advanced users can opt in to newer signature protocols which have not yet been made the default for a particular service/region.
    Not all services support all signature algorithms, and configuring an unsupported signature algorithm will lead to authentication failures. Use me at your own risk, and only after consulting the documentation for the service to ensure it actually does supports your chosen algorithm.
    If non-null, the name returned from this method is used to look up a Signer class implementing the chosen algorithm by the com.amazonaws.auth.SignerFactory class.
    
    Returns:
    The signature algorithm to use for this client, or null to use the default.

  - getConnectionTTL
```
public long getConnectionTTL()
```
    Returns the expiration time (in milliseconds) for a connection in the connection pool. When retrieving a connection from the pool to make a request, the total time that the connection has been open is compared against this value. Connections which have been open for longer are discarded, and if needed a new connection is created.
    Tuning this setting down (together with an appropriately-low setting for Java's DNS cache TTL) ensures that your application will quickly rotate over to new IP addresses when the service begins announcing them through DNS, at the cost of having to re-establish new connections more frequently.
    
    Returns:
    the connection TTL, in milliseconds
  - setConnectionTTL
```
public void setConnectionTTL(long connectionTTL)
```
    Sets the expiration time (in milliseconds) for a connection in the connection pool. When retrieving a connection from the pool to make a request, the total time that the connection has been open is compared against this value. Connections which have been open for longer are discarded, and if needed a new connection is created.
    Tuning this setting down (together with an appropriately-low setting for Java's DNS cache TTL) ensures that your application will quickly rotate over to new IP addresses when the service begins announcing them through DNS, at the cost of having to re-establish new connections more frequently.
    By default, it is set to {@code -1], i.e. connections do not expire.
    
    Parameters:
    connectionTTL - the connection TTL, in milliseconds
  - withConnectionTTL
```
public ClientConfiguration withConnectionTTL(long connectionTTL)
```
    Sets the expiration time (in milliseconds) for a connection in the connection pool. When retrieving a connection from the pool to make a request, the total time that the connection has been open is compared against this value.

    the updated ClientConfiguration object
  - getConnectionMaxIdleMillis
```
public long getConnectionMaxIdleMillis()
```
    Returns the maximum amount of time that an idle connection may sit in the connection pool and still be eligible for reuse. When retrieving a connection from the pool to make a request, the amount of time the connection has been idle is compared against this value. Connections which have been idle for longer are discarded, and if needed a new connection is created.
    Tuning this setting down reduces the likelihood of a race condition (wherein you begin sending a request down a connection which appears to be healthy, but before it arrives the service decides the connection has been idle for too long and closes it) at the cost of having to re-establish new connections more frequently.
    
    Returns:
    the connection maximum idle time, in milliseconds
  - setConnectionMaxIdleMillis
```
public void setConnectionMaxIdleMillis(long connectionMaxIdleMillis)
```
    Sets the maximum amount of time that an idle connection may sit in the connection pool and still be eligible for reuse.

Connections which have been idle for longer are discarded, and if needed a new connection is created.
    Tuning this setting down reduces the likelihood of a race condition (wherein you begin sending a request down a connection which appears to be healthy, but before it arrives the service decides the connection has been idle for too long and closes it) at the cost of having to re-establish new connections more frequently.
    By default, it is set to one minute (60000ms).
    
    Parameters:
    connectionMaxIdleMillis - the connection maximum idle time, in milliseconds
  - withConnectionMaxIdleMillis
