One: Features and comparisons1. Performance: Performance is excellent, specific to the details, because Redis only use single core, and memcached can use multi-core, so on average every core redis in the storage of small data than memcached performance higher.In more than 100k of data,

ObjectiveIn the use of distributed cache, it is inevitable to do such a step, the data is serialized and then stored in the cache.The serialization of this operation, perhaps explicit or implicit, depends on whether the package being used helps us do such a thing.This article uses Redis and memcached in the. NET core environment As an example, where Redis is main
Redis is an advanced Key-value database. It is similar to memcached, but the data can be persisted, and the supported data types are rich, with strings, lists, collections, and ordered collections. Supports the calculation of the aggregation of the set on the server side, and the intersection and complement sets. Multiple sorting functions are also supported. So Redis
Reference a passage in a Chinese article in Python:"Redis is a high-performance Key-value database. The emergence of redis largely compensated for the shortage of keyValue storage such as memcached,It can complement relational databases in different scenarios. It provides python, Ruby, Erlang, and PHP clients for ease of use.The problem is that this project is st

Memcached:
High-performance distributed cache database
Key-value storage mode (HASHMAP)
Data persistence is not supported, all data is lost after server shutdown
C developed, based on the Libevent library, available on most linux,bsd,solaris, as well as in Windows and other OS
The client implements the software in a number of languages: C + +, PHP, Java, Python, Erlang, Perl, Lua,go, etc.

At last year's QCon London2012 conference, Twitter gave a speech entitled "Timelines @ Twitter", which mentioned that Redis is the main storage of its timeline. Currently, it is globally oriented, twitter may be the biggest user of Redis (or Sina Weibo ?).

Tags: Redis, MongoDB and MEMCACRedis (in-memory database) is a Key-value storage system (in-fabric cache, high-performance Key-value database). 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,

What is Redis? Two sentences can be summarized as follows:1. It is a completely open-source and free key-value memory database.2. It is generally considered as a data structure server, mainly because it has a wide range of data structures, such as strings, map, list, sets, and sorted sets.
What is Redis? The comparison is also made from two aspects:1. It is not a relational database such as SQL server or m

If you simply compare the differences between Redis and memcached, most of them will get the following ideas:1 Redis not only supports simple k/v-type data, but also provides storage of data structures such as List,set,hash.2 Redis supports backup of data, that is, Master-slave mode of data backup.3

It is commonly referred to as a data structure server, because the value can be a string (string), a hash (hashes), a list, a collection (sets), and an ordered collection (sorted sets).
