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.

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.

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.
In a real business scenario, you might want to use the Java

Introduction to Transactions
in general, the Java EE Application Server supports JDBC transactions, JTA (Transaction API) transactions (typically managed by a container). In general, it is best not to use the above three transaction types in your program, such as nested JDBC transactions in JTA transactions. Second, the transaction should be completed in as short a time as possible without the use of th
