- Is redis a cache database?
- Yes, Redis is a cache database. Redis (Remote Dictionary Server) is a key-value storage database designed for fast access and storage of data, with high performance, low latency, scalability and durability.

-
- Is redis an open source software?
- Yes, Redis is an open source software. Open source software refers to software whose source code is open to the public, allowing anyone to view, modify and distribute it. Redis is licensed under a BSD 3 license and is available for free. Open source offers many benefits to Redis users, including transparency, customizability, community support, and security.

-
- Are there big differences between the five data types of redis?
- Redis provides five basic data types: string (unstructured binary string), hash (key-value pair set), list (ordered element sequence), set (unduplicated element set), ordered set (with numbers) set of ordered elements). They differ in data structure, operations, memory efficiency, and application scenarios, making them suitable for different use cases.

-
- Does redis have read and write separation?
- Yes, Redis supports read-write separation, which is implemented through replication. The master node is used for writing and the slave node is used for reading. The advantages include improved read performance, failover, load balancing and data consistency. The disadvantages are write delay, Increased complexity and cost.

-
- Does redis need to separate reading and writing?
- Yes, read-write separation is often necessary when using Redis to optimize performance and improve availability. The benefits of read-write separation include: reducing the load on the main server, improving read performance, improving availability, simplifying maintenance, and implementation methods including master-slave replication and the use of middleware. Separation of reading and writing is required in high-concurrency reading and writing scenarios, when high reading performance requirements are required, and when high availability is required. It should be noted that write requests can only be sent to the master server. The slave server data may be slightly delayed, and data consistency issues need to be considered.

-
- Is cache penetration of redis the same as cache penetration?
- No, Redis cache breakdown and penetration are different concepts. Penetration refers to concurrent access to uncached data leading to direct access to the database; penetration refers to malicious requests accessing non-existent data, resulting in misses in both cache and database. The solution is to use mutex locks and parameter verification respectively.

-
- Is redis a non-relational database?
- Redis is a non-relational database that stores data in key-value pairs. It has the characteristics of schema, key-value storage, high concurrency and persistence, and is suitable for scenarios such as caching, session management, queues and distributed locks.
- Redis 650 2024-04-20 05:36:38
-
- Is redis considered a database?
- No, Redis is not a database in the traditional sense. It is an in-memory key-value store used for purposes such as caching, messaging, and session management, but lacks database features such as persistence, transactions, structured data, and query languages.
- Redis 924 2024-04-20 05:32:24
-
- Is redis a memory cache?
- Yes, Redis is an in-memory cache. It stores data in memory, provides high-speed read and write access, low latency, and supports a variety of data structures. It is widely used in applications such as caching, message queuing, session management, and ranked lists.
- Redis 641 2024-04-20 05:26:31
-
- Are redis and mq both middleware?
- Yes, both Redis and MQ are middleware that provide communication and coordination services between applications and operating systems. Redis is a distributed key-value pair data storage that provides fast data access and caching functions; MQ is a messaging system that provides reliable message delivery and queuing functions.

-
- Does redis belong to nosql?
- Yes, Redis is a NoSQL database type. It adopts the key-value storage data model to store data in key-value pairs, and has functions such as caching, session management, real-time analysis, message queues, counters, and rankings.

-
- Is redis nio?
- Yes, Redis is a database using NIO. NIO features include: Multiplexer: handles multiple connections simultaneously. Non-blocking I/O: Redis does not block threads when client operations cannot be completed immediately. Event-driven: Responds to I/O events (e.g., data is readable or writable).

- How to read the latest cache information in redis
- The Redis MONITOR command reads Redis cache information in real time, providing information about executed commands, keys, values, etc. Steps: 1. Connect to the Redis server. 2. Execute the "MONITOR" command. 3. The server will send Redis command execution information in real time. 4. Each line in the event stream represents an executed command, including timestamp, client address, command name and parameters. 5. Press "Ctrl+C" to stop monitoring.

- How redis reads the latest cache file
- In order to read the latest cache file from Redis: trigger RDB persistence through the BGSAVE command, create a data copy and persist the data into the RDB file. Wait for persistence to complete (INFO PERSISTENCE to check progress). An RDB file (usually dump.rdb) is generated when persistence is complete. Use the redis-cli utility to read the RDB file. Parse the data (using a third-party library or manually). Restore data to cache.
