Relational databases have been around for some timeThere are many robust and mature products available Modern database products offer a multitude of features and a host of configuration options One area where difficulty arises is with database features that you do not need or that you should not use for a particular application Applications that have simple data storage requirements do not benefit from the myriad of available options In fact, it can be detrimental in a couple different ways If you need to learn the intricacies of a particular database product before you can make good use of it, the time spent learning takes away from time you could have spent on your application Knowledge of how database products work is good to have It would be hard to argue that you wasted your time by learning it because that information could serve you well far into the future Similarly, if there is a much simpler solution that meets your needs, you could choose that instead If you had no immediate requirement to gain product specific database expertise, it would be hard to insist that you made the wrong choice It is a tough sell to argue that the more time-consuming, yet educational, route is always better than the simple and direct routeThis is a challenge faced by databases today, when the simple problems are not met with simple solutions Another pain point with relational databases is horizontal scaling It is easy to scale a database vertically by beefing up your server because memory and disk drives are inexpensive However, scaling a database across multiple servers can be extremely difficult There is a whole spectrum of options available for horizontal scaling that includes basic master-slave replication as well as complicated sharding strategiesThese solutions each require a different, and sometimes considerable, amount of expertise Nevertheless, they all have one thing in common when compared to vertical scaling solutions On top of the implementation difficulty, each additional server results in an additional increase in ongoing maintenance responsibility Moreover, it is not merely the additional server maintenance of having more servers I am referring to the actual database administration tasks of managing additional replicas, backups, and log shipping It also includes the tasks of rolling out schema changes and new indexes to all servers in the cluster If you are in a situation where you want a simple database solution or you want horizontal scaling, SimpleDB is definitely a service to consider However, you may need to be prepared to defend your decision.

Although keepalive does have some advantages, many developers advocate controlling timeouts and dead sockets at a higher level, in application code It should also be kept in mind that keepalive doesn't allow you to specify a value for probing socket endpoints A better solution than keepalive, and one that developers are advised to use, is to instead modify the timeout socket option 6442 SO_RCVBUF Socket Option The receive buffer socket option controls the buffer used for receiving data Changes can be made to the size by calling the SocketsetReceiveBufferSize(int) method For example, to increase the receive buffer size to 4,096 bytes, the following code would be used

Distributed Array This pattern represents a class of data structures often found in parallel scientific computing, namely arrays of one or more dimensions that are decomposed into subarrays and distributed among processes or threads

// Modify receive buffer size someSocketsetReceiveBufferSize(4096);

All of the program structuring patterns address the same basic problem: how to structure source code to best support algorithm structures of interest Unique forces are applicable to each pattern, but in designing a program around these structures, there are some common forces to consider in most cases:

Note that a request to modify the size of the receive buffer does not guarantee that it will change For example, some operating systems may not allow this socket option to be modified, and will ignore any changes to the value The current buffer size can be determined by invoking the Socket getReceive Buffer Size() method A better choice for buffering is to use a BufferedInput Stream/Buffered Reader 6443 SO_SNDBUF Socket Option The send buffer socket option controls the size of the buffer used for sending data By calling the requests to change the size may be rejected by the operating system
