In this chapter, until now, we have talked about all the data types in Redis. Generally speaking, data in Redis is composed of key-value pairs. Therefore, managing keys is another essential knowledge for application development and administration in Redis. In this recipe, we'll cover keys management.
You need to finish the installation of the Redis Server, as we described in the Downloading and installing Redis recipe in Chapter 1, Getting Started with Redis, and connect to the Redis Server by redis-cli
.
In order to show the keys operation clearly, we first populate some fake data into Redis using fake2db
, with the following steps:
- Install
fake2db
and the Python Redis driver:
$ sudo pip install redis fake2db
Flush all the data of the Redis server:
$ bin/redis-cli flushall
- Populate the testing records to the Redis Server:
$ fake2db --rows 10000 --db redis
