If the MySQL database is large, we can easily find out which tables occupy the space, but if the Redis memory is relatively large, we are not very easy to find out which (kind) keys Occupy space. There are tools that can provide the necessary help, such as redis-rdb-tools can directly analyze the Rdb file to generate the report, but it does not achieve my requirements, and I do not want to build on it two

Redis Remote Dictionary Service--nosql Technology One or five kinds of basic data types String list Hash set sorted set (sorted collection) Two or five kinds of features (1) InMemory in memory similar to cache, is a key-value storage system (2) Weakening the transaction is basically not the concept of a transaction, only in some places the transaction is traversed, and its traversal is not encountered error

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.

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. It provides a variety of mainstream languages for the client, easy to use, while Redis supports master-slave synchronization. In addition to regular numeric values or strings, Redis's key values can also be in
