There is an example of spring-based Redis, which gets Jedis instances from jedisconnectionfactory . The rest of the section ignores only Redisservice, so there are many problems with getting Jedis instances.This way, each new connection is innovated

1. Replication 1,redis uses asynchronous replication. 2, the feature does not block the primary server: even if one or more of the initial synchronizations are in progress from the server, the primary server can continue to process command requests.

The previous one has already told a part of the order of the ordered collection type.http://blog.csdn.net/wtyvhreal/article/details/42804571Third, command supplements1. Get the number of elements in the collectionZcard Key2. Get the number of

The Redis replication (Replication) feature is the implementation of master-slave databases. If you want to improve the efficiency of the request, you can use the primary database for write operations, from the database for read operations. And

Redis is a key, a value database, and a memory database. The architecture of an internet company is now standard. The supported data objects are string, list, set, zest, and hash object. Data: The core structure of the database is dict

Currently, Redis does not have an official HA scenario similar to MySQL proxy or Oracle RAC.The Redis author has a plan called Redis Sentinel, which is said to have three major functions: monitoring, alerting and automatic failover.But unfortunately

About Redis Redis is an open source API that is written in ANSI C, supports the web, can be persisted in memory, key-value databases, and provides multiple languages.Redis is a key-value storage system. Similar to memcached, it supports storing

Set the data expiration time by expire the key seconds command. A return of 1 indicates that the setting was successful, and returning 0 indicates that the key does not exist or the expiration is not successfully set.After the expiration time is set

Although Redis has excellent performance, we can still master/slave this simple architecture, read and write separation, further mining redis performance, improve system availability. How does Redis perform master-slave replication? Redis

In general there are two types of persistence scenarios: Rdb and AoFThe Rdb method creates a point-in-time snapshot of the dataset at certain intervals.The AoF method records the write operations received by the server to the log files and rebuilds

I. What persistence mechanisms are provided by Redis:1). RDB Persistence:The mechanism is to write a snapshot of the in-memory data set to disk within a specified interval of time.2). AoF Persistence:This mechanism will record every write processed

In some usage scenarios, we do not need to use redis persistence, instead we need to play Redis's in-memory database features for full memory operation to achieve the required high performance. The Redis itself supports persistence by

Pick up a Redis Ruby client learning (ii)For the five data types of Redis: string, hash (Map), list, collection (sets) , and ordered collection (sorted sets), the previous article describes the string.1, hash (MAP) Hset. Sets the value of

Environment: Centos 6.2Redis is one of the most popular NoSQL systems today, and it is a key-value storage system. Similar to memcached, but largely compensates for the lack of memcached, which supports storing more value types, including string,
