remember redis after the guarantee can do.
So, before we go into Redis, I'll introduce NoSQL.
Most developers are accustomed to using relational databases. Data-driven development or domain-driven development (as a monolithic framework encoding or NHibernate with the fluent API), the concept of relational databases. NoSQL, on the other hand, ushered in a new fashion for data storage. The most popular amo
as follows:
1) create a redisContext
2) run the command through redisContext
3) obtain the required data from the returned redisReply.
The Code is as follows:
redisContext * c = redisConnect((char *)"192.168.150.135",6379); const char * pData = "this is a test";
redisReply *reply1 = (redisReply *)redisCommand(c,"SET 100 %s",pData);
freeReplyObject(reply1);
redisReply *reply2 = (redisReply *)redisCommand(c,"GET 100");Printf ("% s \ n", reply2-> str );
FreeReplyObject (reply2 );

Redis is very popular in the current technology community. Redis has come a long way from a small personal project from Antirez to becoming the standard in the memory data storage industry. A series of best practices followed, making it possible for most people to use Redis correctly. Below we will explore 10 tips for
A simple Python script that monitors Redis performance has already talked about how to monitor memcached, and now incidentally how to monitor Redis. Let's start with the following information about monitoring redis:

Similar to memcached, it supports storing more value types, including string (string), list (linked list), set (set), Zset (sorted set-ordered collection), and hash (hash type). These data types support Push/pop, Add/remove, and intersection-set and difference sets, and richer opera
When developing an iOS application, it is critical that your program has good performance. This is also what users expect if your program is running slow or slowSlow, will incur the user's bad comment.However, due to the limitations of iOS devices, it is sometimes difficult to get good performance. In the development process, there are many things to remember andAnd it's easy to forget about the

Memcached and Redis Performance test summary– The same data model, memcached can save more heat data than redis, such as memcached in 13G of limited memory can save 100 million data, and Redis probably saved 80 million– the same server environment, memcached write performance

Redis performance testing is accomplished by executing multiple commands at the same time. Redis performance testing is implemented primarily through the Redis

Redis and memcache do not have much difference in write performance, read performance above especially bulk read performance above Memcache fully wins, of course, Redis also has its own advantages: such as data persistence, support more structure (Set List zset), etc.Redis a
