Turn from:Bole Online Java API Design ChecklistEnglish original TheamiableapiThere are always a lot of different specifications and considerations when designing Java Apis. As with any complex thing, this work is often a test of the seriousness of our thinking. Just like the Pilot's checklist before takeoff, this checklist will help software designers recall clea

Common Api-runtime, runable, System classesFirst, the runtime class1. Overview: Runtime classencapsulates the running process of the Java command itselfThat every Java application has a runtime class object that allows it to interact with the running environment while the application is running, but it is important to note that the application itself cannotCreate
The obvious advantage of being able to run the same piece of JavaScript code on both the server and the client is that it enables you to use the same code base for Ajax and non-AJAX clients, and provides more flexibility. For example, if you develop JavaScript code that you don't want others to see, you can run it on a server to protect your intellectual property and minimize security risks. If you don't focus on code protection later, you can move JavaScript code to the client to improve applic
Kudu+impala is a good fit for data analysis, but inserting data directly into the Kudu table using the Insert Values statement is not very efficient, and testing the insert is only 80/sec. The reason is also obvious, the Kudu itself writes very efficiently, But Impala did not do this optimization, observing that each Impala statement executed by the overhead is too large, resulting in frequent small batch write efficiency is very poor, kudu is officially recommended to use the

Kafka ---- kafka API (java version), kafka ---- kafkaapi
Apache Kafka contains new Java clients that will replace existing Scala clients, but they will remain for a while for compatibility. You can call these clients through some separate jar packages. These packages have little dependencies, and the old Scala client will still exist.
I. Producer
Summary: The development of Java Mail API is a good example of SUN's continuous efforts to provide a public API framework for Java developers. A public framework is promoted to oppose solutions restricted by suppliers, which fully predicts the establishment of an increasingly open development environment.The structure

DAO is called data Access objectThe DTO is a data transfer objectDAO is often manipulated by objects, such as data in a relational database, that are not object-like.The DTO is typically used for direct data transmission at different layers (UI layer, service layer, or domain model layer) to isolate different layers and reduce coupling between layersIt's supposed to be Java beans for Jackson and XStream.

Java API Read hive orc file
Reprint: http://lxw1234.com/archives/2015/08/462.htm
Orc is a hive-specific file format that has a very high compression ratio and read efficiency, so it quickly replaces the previous rcfile and becomes a very common file format in hive.

Windows OS users are familiar with Excel (workbooks), but it is not easy to use Java to manipulate Excel files. As web applications are becoming increasingly popular today, the demand for using web to Operate Excel files is getting stronger and stronger. Currently, a popular operation is to create a CSV (comma separated values) file in JSP or servlet, the file is returned to the browser as mime, text/CSV, and then the browser calls Excel and displays
