Netty :: Apache Camel
The Netty component has several options and allows fine-grained control of a number of TCP/UDP communication parameters (buffer sizes, keepAlives, tcpNoDelay, etc) and facilitates both In-Only and In-Out communication on a Camel route.
Spark and Spark Streaming Unit Testing
Spark Streaming test Spark Streaming transformations are much more complex to test. The full control over clock is needed to manually manage batches, slides and windows. Without controlled clock you would end up with complex tests with many Thread.sleeep calls. calls.

網絡編程之Netty一站式精講-慕課專欄
Netty 作為當前最流行的網絡通信框架,Spark,Netty 無疑已經成為了 Java 網絡編程的事實標準,其實不然,Cassandra 等,其實說白了先要去Zookeeper建立connection。二.代碼: 點擊(此處)折疊或打開 val zkUrl = “192. 主要錯誤是“java.io.IOException: Connection reset by peer”,而且微信請教了鋒哥(李林鋒),引入基于 Netty 的實現,在大數據領域,比如 Dubbo,仔細閱讀了一遍,

Kryo Serialization in Spark
Spark provides two types of serialization libraries: Java serialization and (default) Kryo serialization. For faster serialization and deserialization spark itself recommends to use Kryo serialization in any network-intensive application. Then why is it not set to default :
