How SpringBoot monitors redis Key change events How SpringBoot monitors redis Key change events May 26, 2023 pm 01:55 PM

1. Function Overview Keyspace notification allows clients to receive events that modify Rediskey changes in some way by subscribing to channels or patterns. All commands that modify key keys. All keys that received the LPUSHkeyvalue[value…] command. All expired keys in the db database. Events are distributed through Redis's subscription and publishing functions (pub/sub), so all clients that support subscription and publishing functions can directly use the keyspace notification function without any modifications. Because the current subscription and publishing functions of Redis adopt a fireandforget strategy, if your program

Implementing dynamic arrays in Python: from beginner to proficient Implementing dynamic arrays in Python: from beginner to proficient Apr 21, 2023 pm 12:04 PM

Part 1 Let’s talk about the nature of Python sequence types. In this blog, let’s talk about Python’s various “sequence” classes and the three built-in commonly used data structures – list, tuple and character. The nature of the string class (str). I don’t know if you have noticed it, but these classes have an obvious commonality. They can be used to save multiple data elements. The most important function is: each class supports subscript (index) access to the elements of the sequence, such as using SyntaxSeq[i]​. In fact, each of the above classes is represented by a simple data structure such as an array. However, readers familiar with Python may know that these three data structures have some differences: for example, tuples and strings cannot be modified, while lists can.

How to solve the problem of batch deletion of key values ​​in redis How to solve the problem of batch deletion of key values ​​in redis May 31, 2023 am 08:59 AM

Problems encountered: During the development process, you will encounter keys that need to be deleted in batches according to certain rules, such as login_logID (ID is a variable). Now you need to delete data such as "login_log*", but redis itself only has batch query. Command keys for class key values, but there is no command for batch deletion of a certain class. Solution: Query first, then delete, use xargs to pass parameters (xargs can convert pipe or standard input (stdin) data into command line parameters), execute the query statement first, and then remove the queried key value and the original del parameters. delete. redis-cliKEYSkey* (search condition)|xargsr

What is the type of return value of Golang function? What is the type of return value of Golang function? Apr 13, 2024 pm 05:42 PM

Go functions can return multiple values ​​of different types. The return value type is specified in the function signature and returned through the return statement. For example, a function can return an integer and a string: funcgetDetails()(int,string). In practice, a function that calculates the area of ​​a circle can return the area and an optional error: funccircleArea(radiusfloat64)(float64,error). Note: If the function signature does not specify a type, a null value is returned; it is recommended to use a return statement with an explicit type declaration to improve readability.
