How many requests Redis can handle?

Question

Using a single-node instance of Redis running on my laptop I managed to get 300K requests per second (both get and set). This is achieved only if using pipelining (100 commands at a time). On a high-end machine someone got 700K get requests per second using pipelining, i.e. a bit more than twice the throughput. 27 авг. 2013 г.

How much data can Redis handle?

Redis can handle up to 2^32 keys, and was tested in practice to handle at least 250 million keys per instance. Every hash, list, set, and sorted set, can hold 2^32 elements. In other words your limit is likely the available memory in your system.

How many RPS can Redis handle?

Yes, because as you can see in the table above, for 30-KB key size Redis is capable of handling 940 RPS.

How many QPS can Redis handle?

For small packets, a Redis server can process 80,000 to 100,000 QPS. A larger QPS is beyond the processing capacity of a Redis server. A common solution is to partition the data and adopt multiple servers in distributed architecture.

How concurrency is handled in Redis?

RediSearch has a thread pool for running concurrent search queries. When a search request arrives, it gets to the handler, gets parsed on the main thread, and a request object is passed to the thread pool via a queue. The thread pool runs a query processing function in its own thread.
