ObjectiveWhen we talk about database schema and database optimization, we often hear "sub-database", "Shard", "sharding" ... Such a keyword. Happily, the number of companies that these friends are serving is (or is about to be) growing at a rapid pace, and technology faces some challenges.What worries people is that they really need a "sub-database"? Is the "sub-

Question: enter an integer array with a positive or negative number in the array. One or more consecutive integers in the array form a sub-array. Each sub-array has a sum. Returns the maximum value of the sum of all sub-arrays. The time complexity is O (n ). For example, the input array is 1,-2, 3, 10,-4, 7, 2,-5, and the maximum

. In addition, the sub-bean configuration can add new configuration information, the new configuration information can overwrite the definition of the parent bean. Child beans cannot inherit the following attributes from the parent Bean: depends-on, autowire, Singleton, scope, and lazy-init. These attributes will always be obtained from the Child bean definition or take the default value. By specifying a Parent attributesYou can specify that the b

In vs2005, subthreads are not allowed to use controls in the UI. The solutions on the Internet include: using controls for invoke. However, in my own applications, it is always troublesome: I want to call the processing in a main thread from the Child thread. I need to use a delegate, while the invoke still needs to use the delegate to bypass and confuse people. I slightly changed the structure to make it easier to call the handler in the UI thread in the Child thread. In the Thread class,

very clear and clear in some problem areas may become less clear when implemented. As programmers, using clean code to achieve functionality is only a primary requirement, more importantly, to improve the level of common language, to build a specific problem domain language (DSL), the process is a key point is to find and define the problem domain-oriented atomic concepts, Combination of methods and abstract means . The DSL does not have to be as complete as the universal language, and its goal

What is the difference between a sub and a function, and how should their grammar be constituted? Sub: Process; Function: Functions, can be returned with a value Grammar: Sub subname (parameter 1, parameter 2,...) .... End Sub Function functionname (parameter 1, parameter 2,...) ... functionname = return value End Func

The structure of the iterator (iterator) pattern: An iterative child pattern can sequentially access elements in a cluster without exposing the internal representation of the aggregation. iterations can be divided into external iteration Sub and intrinsic iteration Sub . External Iteration Child: The is suitable for white box aggregation (white box aggregation is to provide external access to t

Sometimes the need to load the table by default when the table data is also shown, after studying the relevant Subgrids API configuration is as follows: Properties type Description Default Value Subgrid Boolean Set to True to enable the sub-table. If you enable a sub-table, additional columns are added to the left of the parent table. This column contains

that the data path can be clean and controllable without relying on the clock. However, asynchronous resetting also has inherent defects. The DFT (testability design) and sta (static timing analysis) of Asynchronous Reset design are more complex than Synchronous Reset design. However, the most serious problem in Asynchronous Reset is that, if the Asynchronous Reset signal is "released" when the trigger clock is effective (the reset signal changes from effective to invalid), it may cause the

(subscriber). The client sends the message to the topic. Multiple publishers send messages to topic, which the system passes to multiple subscribers. Each message can have multiple consumers There is a time dependency between the Publisher and the Subscriber. Subscribers to a topic (TOPIC) must create a subscription before they can consume the publisher's message and, in order to consume the message, the Subscriber must remain in a running state.Of course, to mitigate this strict time depende
