1问题描述基于Web服务的应用在传输大数据时所面临的主要问题如下:1.1性能一般来说,一个Web服务应用主要由服务器端、客户端和SOAP引擎组成。当通过SOAP消息体来传输大数据时,SOAP引擎将处理整个数据,因而需要不可预知的大量内存来创建如此大的SOAP消息体;而如果通过加密通道来传输时,服务器端和客户端都需要进行额外的加密和解密处理。所有的这些因素将导致整个Web服务的性能下降。
1 Problem Description Web service-based applications in the transmission of big data are faced with the following major issues: 1.1 Performance In general, a Web service applications mainly by the server-side, client and SOAP engine. When big data is transmitted through a SOAP body, the SOAP engine processes the entire data, requiring unpredictable amounts of memory to create such a large body of SOAP messages; both server-side and client-side needs to be transmitted over the encrypted channel For additional encryption and decryption processing. All of these factors will lead to the performance degradation of the entire Web service.
