For large-scale PHP applications, what application is usually used for message queue?
I have been using Redis as a message queue, and suddenly I thought, is there a better one?
Reply content:
We use beanstalk, qps is about 1000 If you are simply doing queue services, I recommend beanstalkd (small, good performance). If you consider high availability and massive volume, you can use kafka. Why don't you first point out the aspects of the existing solutions that are not good enough? I feel like this problem has nothing to do with PHP? Message queue selection more considers business scenarios:* Performance, such as how many messages are there per second. If you have tens of thousands of messages per second, then Beanstalk and RabbitMQ cannot be used directly.
* Reliability, are messages allowed to be lost? Is persistence required?
* High availability, can downtime be tolerated?
* Whether distribution is needed
* Operation and maintenance costs, whether your company's development (operation and maintenance) has the ability to maintain this message queue
* Client support, this is something at the language level. For example, Kafka is a very good message queue, but its PHP client is not very well written, and it is difficult to rewrite it yourself, so you should be careful when choosing one.
After weighing these factors, you can decide how to choose.
What message queues are there: Message queue
Performance comparison: http://bravenewgeek.com/dissecting-message-queues/ redis,rabbitmq Use redis and rabbitmq This depends on your application scenario. Generally speaking, it is relatively simple to use redis, but redis cannot realize the situation where the message is not processed normally and other processes can still process the message, that is, there is no process of confirming the completion of processing of the message.
If you want a complete message queue, the ones I have used include: gearman and rabbitmq, both of which are good. php-resque gearman. If you require no message loss across networks, you can also choose kafka worker

Redis cluster mode deploys Redis instances to multiple servers through sharding, improving scalability and availability. The construction steps are as follows: Create odd Redis instances with different ports; Create 3 sentinel instances, monitor Redis instances and failover; configure sentinel configuration files, add monitoring Redis instance information and failover settings; configure Redis instance configuration files, enable cluster mode and specify the cluster information file path; create nodes.conf file, containing information of each Redis instance; start the cluster, execute the create command to create a cluster and specify the number of replicas; log in to the cluster to execute the CLUSTER INFO command to verify the cluster status; make

Using the Redis directive requires the following steps: Open the Redis client. Enter the command (verb key value). Provides the required parameters (varies from instruction to instruction). Press Enter to execute the command. Redis returns a response indicating the result of the operation (usually OK or -ERR).

How to clear Redis data: Use the FLUSHALL command to clear all key values. Use the FLUSHDB command to clear the key value of the currently selected database. Use SELECT to switch databases, and then use FLUSHDB to clear multiple databases. Use the DEL command to delete a specific key. Use the redis-cli tool to clear the data.

Redis uses a single threaded architecture to provide high performance, simplicity, and consistency. It utilizes I/O multiplexing, event loops, non-blocking I/O, and shared memory to improve concurrency, but with limitations of concurrency limitations, single point of failure, and unsuitable for write-intensive workloads.

The best way to understand Redis source code is to go step by step: get familiar with the basics of Redis. Select a specific module or function as the starting point. Start with the entry point of the module or function and view the code line by line. View the code through the function call chain. Be familiar with the underlying data structures used by Redis. Identify the algorithm used by Redis.

To read a queue from Redis, you need to get the queue name, read the elements using the LPOP command, and process the empty queue. The specific steps are as follows: Get the queue name: name it with the prefix of "queue:" such as "queue:my-queue". Use the LPOP command: Eject the element from the head of the queue and return its value, such as LPOP queue:my-queue. Processing empty queues: If the queue is empty, LPOP returns nil, and you can check whether the queue exists before reading the element.

To view all keys in Redis, there are three ways: use the KEYS command to return all keys that match the specified pattern; use the SCAN command to iterate over the keys and return a set of keys; use the INFO command to get the total number of keys.

Redis uses hash tables to store data and supports data structures such as strings, lists, hash tables, collections and ordered collections. Redis persists data through snapshots (RDB) and append write-only (AOF) mechanisms. Redis uses master-slave replication to improve data availability. Redis uses a single-threaded event loop to handle connections and commands to ensure data atomicity and consistency. Redis sets the expiration time for the key and uses the lazy delete mechanism to delete the expiration key.
