redis Concurrent requests key value pair

Redis counter is a mechanism that uses Redis key-value pair storage to implement counting operations, including the following steps: creating counter keys, increasing counts, decreasing counts, resetting counts, and obtaining counts. The advantages of Redis counters include fast speed, high concurrency, durability and simplicity and ease of use. It can be used in scenarios such as user access counting, real-time metric tracking, game scores and rankings, and order processing counting.

How to implement redis counter

Redis counter implementation

Redis counter is a mechanism that uses Redis key-value pair storage to implement counting operations. It provides an easy and efficient way to increase, decrease or reset counter values.

Implementation steps:

  1. Create Counter Keys: Use the INCR command to create a key-value pair containing a unique key. For example: INCR my_counter .
  2. Increasing Count: Use the INCR command to increase the counter's value. For example: INCR my_counter 5 increases the counter by 5.
  3. Decrease Count: Use the DECR command to reduce the value of the counter. For example: DECR my_counter 3 decrements the counter.
  4. Reset Count: Use the DEL command to delete the counter key-value pair. For example: DEL my_counter resets the counter to 0.
  5. Get Count: Use the GET command to get the current value of the counter. For example: GET my_counter will return the value of the counter.

Advantages:

  • Fast speed: Redis's atomic operation ensures fast and consistent counter updates.
  • High Concurrency: Redis can handle a large number of concurrent requests, making it suitable for high-traffic applications.
  • Persistence: Redis can be configured for persistence to ensure that the counter value is not lost even if the server goes down.
  • Easy to use: Redis provides simple and easy to use commands without complex coding.

Application scenarios:

Redis counters are widely used in the following scenarios:

  • User access count
  • Real-time metric tracking
  • Game scores and rankings
  • Order processing count

Usage of map in java Key-value pair operation techniques for Map collections Usage of map in java Key-value pair operation techniques for Map collections May 28, 2025 pm 05:54 PM

Map collections in Java are powerful tools for handling key-value pairs of data. 1) Use HashMap to perform basic operations, such as storing and retrieving data, with an average time complexity of O(1). 2) Use getOrDefault method to count word frequency and avoid null value checking. 3) Use TreeMap to automatically sort key-value pairs. 4) Pay attention to the duplication of key-value pairs, and use putIfAbsent to avoid overwriting old values. 5) When optimizing HashMap performance, specify the initial capacity and load factor.

Redis: Understanding Its Architecture and Purpose Redis: Understanding Its Architecture and Purpose Apr 26, 2025 am 12:11 AM

Redis is a memory data structure storage system, mainly used as a database, cache and message broker. Its core features include single-threaded model, I/O multiplexing, persistence mechanism, replication and clustering functions. Redis is commonly used in practical applications for caching, session storage, and message queues. It can significantly improve its performance by selecting the right data structure, using pipelines and transactions, and monitoring and tuning.
