redis cluster transaction

When it comes to redis migration, it is common to use an RDB or aof to do an automatic reload to the target library method in the main library. However, the problem of this method is that there is no guarantee that the source node data and the target node data are consistent, the general line environment does not allow the source library to stop, so after the migration process to achieve synchronization to achieve data consistency. The company's onlin

the WATCH execution and before the EXEC execution, the transaction of the current client will fail. What the program needs to do is to retry the operation until there is no collision.This form of lock is called optimistic lock, which is a very powerful lock mechanism. In addition, in most cases, different clients access different keys, and there are usually few collisions. Therefore, Retry is usually not required. Install and test

First, you need to install GCC before installing Redis:Yum Install GCC-c++. 1, download the Redis source package2, upload the source package to the Linux server3, unzip the source package:Tar-ZVXF redis-3.0.0-Tar. GZ4， Make5， Makeinstallprefix=/usr/local/Redis: Specify the installation directory so you can. Next, Redis

This article mainly introduces the Redis cluster specification detailed, we will from the most basic of what is the Redis cluster and the function of Redis cluster solution, involving node failure detection,

Redis is an open source, C-based, memory-based, and persistent, high-performance NoSQL database, and it also provides APIs in multiple languages. Recently, Redis 3.0 after 6 RC version, its official version finally released. The most important feature of Redis 3.0 is the support for Redis clusters, which has been signi

Some time ago interviewed Alibaba, the interviewer asked me in addition to Redis 3.0 development of the official Redis cluster mode (http://www.redis.cn/topics/cluster-tutorial.html), What other Redis cluster scenarios do you know

introduction of distributed characteristics of Redis Sentinel Redis Sentinel is a distributed system that is designed to operate in an environment where many sentinel processes cooperate with one another. The advantages of having many sentinel processes cooperating with each other are as follows: When multiple Sentinel agree that a master is no longer available, fault detection is performed. This significan

The goal of Redis is to be concise and efficient, because the transaction itself is a complex thing, and all we can't do is complicate the transaction ... multi，exec 127.0.0.1:6379> multi OK 127.0.0.1:6379> lpush fruits orange QUEUED 127.0.0.1:6379> lpush fruits nut QUEUED 127.0.0.1:6379> lpush fruits apple QUEUED 127.0.0.1:

This paper mainly introduces a high availability scheme of Redis cluster through Jedissentinel, this scheme needs to use Jedis2.2.2 and above (mandatory), Redis2.8 and above (optional, Sentinel first appeared in the Redis2.4, Redis2.8 Sentinel more stable, Redis cluster is a shard (sharding) plus master-slave way to bu

There are two ways PHP will operate the Redis cluster cluster:1, use Phpredis extension, this is a C extension, performance is higher, but phpredis2.x extension does not, need to upgrade Phpredis to 3.0, but this program reference very few2, using Predis, pure PHP development, using the namespace, need to php5.3+, high flexibilityI'm using Predis, and I'm loading

I. Note that the redis3.0 cluster has been available for some time. Currently, the latest stable version is 3.0.5. I have learned that many Internet companies are using it in production environments, such as weipinhui and Meituan, just as the company has a new project, the estimated volume of Single-host redis cannot be met, and the development does not want to split it at the code level, so we recommend th

Recently in the study of Redis cluster solution, see a friend wrote a good point of view, it was first collected. See the original: http://www.zhihu.com/question/21419897Why cluster?In general, in order to improve the responsiveness of the website, the hotspot data is always kept in memory instead of being read directly from the backend database.
