"Editor's note" in the famous tweet debate: MicroServices vs. Monolithic, we shared the debate on the microservices of Netflix, Thougtworks and Etsy engineers. After watching the whole debate, perhaps a large majority of people will agree with the service-oriented architecture. In fact, however, MicroServices's implementation is not simple. So how do you build an efficient service-oriented architecture? Here we might as well look to mixrad ...

DoS (Denial of service), the abbreviation for Denial-of-service, refers to the intentional attack on the network protocol implementation of the flaw or directly through brute means to deplete the object of the target resources, the purpose is to make the destination computer or network can not provide normal services, so that the target system stop responding to even crash. These service resources include network bandwidth, file system space capacity, open processes, or allowed connections. This attack will lead to a lack of resources, no matter how fast the processing speed of the computer, the amount of memory, the speed of network bandwidth can not avoid the impact of this attack. ...

However, in the application scenario of data analysis, some mature data analysis tools (such as Tableau, Excel, etc.) require the user to provide an ODBC data source, in which case the REST service does not meet the user's need for data usage. This article provides a detailed overview of how to develop a custom ODBC driver based on the existing rest service from an implementation perspective. The article focuses on the introduction of ODBC ...
