Editor to share with you what is the difference between redis and hbase, I believe that most people still do not understand, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

HBase and Redis are functionally similar. They are all nosql-type databases. However, in the applicable scenario, there is still an obvious difference between the two.

The following is based on read and write performance, data type, data volume, deployment difficulty, data reliability, application scenario, combination of the two and other dimensions to compare the two.

Read and write performance:

HBase writes fast and reads slowly. The read time of HBase is usually a few milliseconds, while that of Redis is usually tens of microseconds. The performance varies greatly.

Data type:

Both HBase and Redis support the KV type. But Redis supports richer types like List, Set, and so on.

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 the size of memory.

Deployment is difficult and easy:

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

Data reliability:

HBase uses WAL, which records the log first and then writes the data. Theoretically, the data will not be lost. Redis, on the other hand, replicates data asynchronously and may lose data during failover.

Application scenarios:

HBase is suitable for big data's persistent storage, while Redis is more suitable for caching. If data loss is intolerable, then only use HBase;. If you need a high-performance environment and can tolerate a certain amount of data loss, you can consider using Redis.

The combination of the two:

HBase can be used to solidify data, that is, data storage, which is very suitable for him. Redis is suitable for cache. HBase+Redis can be used to realize data warehouse and cache database, taking into account both speed and scalability.

The above is all the content of what is the difference between redis and hbase. Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
