This article is about the difference between HBase and Redis. Xiao Bian thinks it is quite practical, so share it for everyone to make a reference. Let's follow the editor and have a look.

HBase and Redis are functionally similar. All are databases of type nosql. However, in terms of applicable scenarios, there are still obvious differences between the two.

read and write performance

HBase writes fast and reads slowly. HBase reads in milliseconds, while Redis reads in microseconds. The performance varies greatly.

data type

Both HBase and Redis support KV types. But Redis supports richer types such as List and Set.

amount of data

The amount of data supported by Redis is usually limited by memory, while HBase does not have this limit and can store data that far exceeds memory size.

deployment difficulty

HBase deployment relies on services such as hadoop and zookeeper, while Redis deployment is very simple.

data reliability

HBase uses WAL to record logs first and then write data, theoretically without losing data. Redis, on the other hand, uses asynchronous replication of data, which may be lost during failover.

application scenarios

HBase is suitable for persistent storage of large data, while Redis is more suitable for caching. If data loss is intolerable, use HBase only; if you need a high-performance environment that tolerates some data loss, consider Redis.

HBase can be used to solidify data, that is, data storage, and it is very suitable for doing this. Redis is suitable for cache. HBase+Redis can be used to achieve a data warehouse plus cache database, both speed and scalability.

Comparing the above, we can see. Both have their own areas of expertise, and there is no substitution for each other. For specific service selection, the most appropriate solution shall be selected according to specific business scenarios and data volume.

Thank you for reading! What is the difference between HBase and Redis is shared here. I hope the above content can be of some help to everyone so that everyone can learn more. If you think the article is good, you can share it so that more people can see it!
