Memcached vs. RedisDB/InMemory 2019. 9. 29. 13:54
1. Overview Both tools are powerful, fast, in-memory data stores that are useful as a cache. Both can help speed up your application by caching database results, HTML fragments, or anything else that might be expensive to generate. But Redis is more powerful, more popular, and better supported than Memcached. Memcached can only do a small fraction of the things Redis can do. Redis is better even..

Cache, Write-through, and Write-backDB/InMemory 2019. 9. 29. 12:36
1. Overview A caching method in which modifications to data in the cache aren't copied to the cache source until absolutely necessary. Write-back caching is available on many microprocessors, including all Intel processors since the 80486. With these microprocessors, data modifications (e.g., write operations) to data stored in the L1 cache aren't copied to main memory such as RAM. until absolut..

Remote Dictionary Server(Redis) and Redis Enterprise ClusterDB/InMemory 2019. 8. 25. 08:18
1. Overview An in-memory data structure project implementing a distributed, in-memory key-value database with optional durability. Redis supports different kinds of abstract data structures, such as strings, lists, maps, sets, sorted sets, HyperLogLogs, bitmaps, streams, and spatial indexes. 2. Description 2.1 Differences with other database systems 2.1.1 Can be considered either a store and a c..
