Finding the causes of slow responses This document will help you understand what the problem could be if you are experiencing latency problems with Redis. In this context latency is the maximum delay between the time a client issues a command and the time the reply to the command is received by the client. Usually Redis processing time is extremely low, in the sub microsecond range, but there are

How Redis writes data to disk Persistence refers to the writing of data to durable storage, such as a solid-state disk (SSD). Redis provides a range of persistence options. These include: RDB (Redis Database): RDB persistence performs point-in-time snapshots of your dataset at specified intervals. AOF (Append Only File): AOF persistence logs every write operation received by the server. These oper

Redis Cluster a pragmatic approach to distribution All nodes are directly connected with a service channel. TCP baseport+4000, example 6379 -> 10379. Node to Node protocol is binary, optimized for bandwidth and speed. Clients talk to nodes as usually, using ascii protocol, with minor additions. Nodes don't proxy queries. What nodes talk about?

Introduction to Redis streams A Redis stream is a data structure that acts like an append-only log but also implements several operations to overcome some of the limits of a typical append-only log. These include random access in O(1) time and complex consumption strategies, such as consumer groups. You can use streams to record and simultaneously syndicate events in real time.

Simple strings Simple strings are encoded as a plus (+) character, followed by a string. The string mustn't contain a CR (\r) or LF (\n) character and is terminated by CRLF (i.e., \r\n). Simple strings transmit short, non-binary strings with minimal overhead. For example, many Redis commands reply with just "OK" on success. The encoding of this Simple String is the following 5 bytes: +OK\r\n When
