红色的面试之旅层层深入 Redis（redis 面试连环问）
的世界
As a programmer, interviews are a necessary step in our career development. It’s a bumpy journey, but it’s full of joy when you accomplish your goal. In this article, I’d like to share my interview journey with Redis, and how I step by step plunge into its world.
Redis is an open source in-memory data structure store. It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs and geospatial indexes. It is well-suited for use as a database, cache, message broker and also provides us with the powerful Pub/Sub feature.
My journey with Redis started with reading the official documentation. As I was trying to systemize my knowledge, my understanding of Redis quickly grew. I wrote small programs to test the various operations and I went through the source code of Redis to understand its internal workings.
In my interview, I started the discussion by explning the advantages of using Redis. I discussed with my interviewer the scalability, high avlability, replicability and sharding features which Redis provides. I also added some tips to optimize the performance of Redis. I deployed an in-memory Redis server and discussed the usage of different data structures to solve several problems. I also showcased my proficiency with Redis by writing a few programs using the libraries and explned the different commands I used for programming with rredis.
Then I had the opportunity to install Redis in a production environment. I was able to showcase my knowledge and skills in setting up a Redis cluster with full replication that handled client requests with maximum speed and efficiency. I also made sure I was familiar with the Open Source projects management system and was able to expln various monitoring tools used for different purposes.
Overall, my Redis experience made me understand its true potential and this knowledge has helped me in becoming a successful programmer. I’d like to encourage all the programmers to keep the learning trend going and try their luck with the application of data structures and coding techniques.
In conclusion, my Redis interview experience was an enlightening one. Not only did I gn a valuable insight into how a technology such as Redis works, but I also gned confidence in myself to solve any type of challenging problem. I’m grateful for this journey and am looking forward to master other technologies as well.
