Data partitioningRedis clusters store data on multiple nodes, that is, different partitions are stored on different nodes, and each node can store multiple partitions. Each partition is also referred to as a "hash slot" in Redis, with a total of 16,384 partitions planned in the Redis cluster. For example: when there are 3 nodes in a cluster, Node A will contain 0-5460 partitions, Node B will contain 5461-10

Redis is a high-performance key-value database. The emergence of redis largely compensates for the shortage of keyvalue storage such as memcached, and can play a very good complementary role in relational databases. It provides Python, Ruby, Erlang, PHP, and Java clients for ease of use.Redis uses a single-thread IO multiplexing model and encapsulates a simple Ae

In. net, axWinsock listens to multiple clients.
There is little information on the axWinsock controls in. net on the Internet, and there are even fewer cases.
AxWinsock has been suffering some time ago from listening to multiple clients. Now I finally got it out, hoping to help people who need it.

If you are not familiar with network programming, we recommend that you first learn the network programming section of Linux + signal model (or Windows Network Programming + complete port model ). Ace is a good package. It encapsulates these models, but there is no good theoretical basis. It is unlikely to design a high-performance network server.
For more information about network server models, see c10k. Of course, in Linux, the best model would be epoll ?). Currently, a server supports access
Client and server program templates supported by network programming:
1. connect multiple clients to the server at the same time, that is, the service program can serve multiple clients at the same time;
2. The server supports socket pair reuse, that is, even in the time_wait status, the server can be restarted;
3. The server can check whether the client is disconnected;
4. The standard input of the client
3. Updater Application Block: This module is mainly responsible for automatic updating of programs. In the fat client mode, it is very troublesome to deploy and update programs. Especially when there are hundreds of clients, we have to process them one by one, in this way, we will waste a lot of time and energy, and it is very easy to make mistakes. The Updater Application Block provides a good solution. Each time the client starts, the program checks
