SQL Server is a set of RDBMS. The functions of this product are not much said. In the real world, databases are often used as data storage and analysis platforms, however, some application scenarios are not suitable for database analysis and processing, especially for scenarios with high processing capacity and low latency. Currently, data in SQL Server is persisted through memory + disk. In other words, data in SQL will ce

, the idea of decomposing process information in an ESB can be borrowed, but we can do it in a simpler way.
The way of realizing EDA
In EDA, the event processing model can be divided into the following three types according to the simple degree of the event:
Simple event handling (processing)
Stream event Processing (stream events processing)
Complex incident handling (Complex event processing, CEP)

Sper is a Java-developed event stream processing (ESP: event stream processing) and complex event processing (CEP: complex event processing) engine. CEP: a technology that processes real-time events and mines complex patterns from a large number of event data streams. ESP: a technology that filters, analyzes, and obtains meaningful information from a large number of event data streams in real time. This eng
I have always been puzzled by the understanding of complex event processing (CEP)-Why is this computational model effective and able to analyze and get useful results? Why is it fast? I still haven't found the answer I expected. Unlike the Map-reduce model, Google's paper describes its scene very clearly, or the disruptor framework, which clearly explains why it is fast. In trying to understand the CEP, I a

For real-time information analysis and processing, it is often necessary to develop the corresponding functions of the customer application. In general, these functions need to provide the following processing procedures, analyze the acquired data, filter the data, extract useful information, and then display it in a specific form. Because of the high concurrency and high throughput requirements of specific real-time information, this requires the customer's applications to have high scalability

UtcClockProvider must be used to support multiple time zones. If UtcClockProvider is used, all date values are stored in UTC and sent to the client in UTC format, then, we can convert the UTC date to the user's time zone through the user's current time zone settings on the client.

generally a combination of simple events. However, a simple Data Stream Management System (DSMs) can only process filtering and aggregation of simple events, the concept of complex events is not supported. Therefore, it is necessary to build a Complex Event Processing System (CEP) on the data stream to meet such requirements. Because domain practice is the result of years of experience in a specific business unit, it is difficult to expect a single s
