Editor to share with you whether redis can be used as a database depends on what conditions, I hope you will learn a lot after reading this article, let's discuss it!

Whether redis can be used as a database depends on the following conditions:

1: the amount of data, after all, the in-memory database, is still limited by the capacity of memory, although redis can be persisted.

2: the data structure, whether the relational data structure can be transformed into the form of key/value.

3: the efficiency of the query, whether the range query can be converted into an efficient hash index query

Whether redis can be used as a database depends on what data you want to store:

If you plan to store some temporary data, the scale of the data is small, do not need too complex queries, but the performance requirements are high, then you can use redis as a database.

Otherwise, don't use it as a database.

Whether redis can do the database depends on your specific needs:

1. As mentioned above, there is a problem with the persistence of redis. If you use aof mode and fsync always, the performance is lower than mysql. If you like the convenient data structure of redis and do not require high performance, or high performance requirements, but allow a certain degree of data loss, you can use redis as a database.

2. Redis is an in-memory database. After the memory is full, the data will not be stored on the hard disk (VM is unstable, diskstore is not enabled). If your memory is large enough, you can use redis as the database.

Redis is a kind of in-memory database of KBE, which is suitable for the storage of small amount of data and places with high real-time requirements, but it is not suitable to be a complete database. The complete database basically has a set of detailed solutions that have not been done, such as mysql.

The redis used in the project is used for caching, set the expiration time, and then automatically clear it. The database still uses mature schemes such as mysql.

If you have to use a nosql as a database, it is recommended that you use Mongodb.

This kind of KV storage does not have the data security guarantee that the database can provide.

So it is more appropriate to use it as a cache.

It is unreliable for redis to make a database. Not all data is written back to disk immediately.

After reading this article, I believe you have a certain understanding of the conditions under which redis can be used as a database. If you want to know more about it, you are welcome to follow the industry information channel. Thank you for your reading!
