Big和large的区别

Big和large都表示“大”的意思,但是它们的使用场合略有不同。Big通常用于描述物体的体积或者数量的多少,而large则更多用于描述物体的尺寸或者范围的大小。例如,我们可以说一个大箱子(a big box),但是如果要描述一个大型建筑物,我们会用large,比如a large building。

bigdata flume
Flume is an open-source tool for efficiently collecting, aggregating, and moving large amounts of data from various sources to a centralized store such as HDFS (Hadoop Distributed File System). Flume is a distributed, reliable, and available service that is used to efficiently collect, aggregate, and move large amounts of log data from different sources to a centralized data store in Hadoop.
In the context of big data, Flume can be used to collect data from various sources such as social media, sensor networks, application logs, and web server logs, and store it in Hadoop for processing and analysis. Flume can handle huge amounts of data and can scale horizontally to accommodate more data sources and higher volumes of data.
Flume architecture consists of three main components: the source, the channel, and the sink. The source is responsible for collecting and forwarding data to the channel, which acts as a buffer for the data. The sink then extracts the data from the channel and stores it in Hadoop.
Overall, Flume is an essential tool in the big data ecosystem for efficiently moving and processing large amounts of data.
oracle blob bigendian
Oracle中的BLOB(Binary Large Object)数据类型用于存储二进制数据,如图像、音频和视频等。BLOB数据是以字节序列的形式存储的,而字节序指的是在一个多字节的数据类型中,字节的顺序排列方式。
在计算机中,字节可以根据存储的方式分为大端序(Big-Endian)和小端序(Little-Endian)。大端序是指在一个多字节的数据类型中,高位字节存储在低地址,而小端序则是高位字节存储在高地址。
当提到Oracle中的BLOB数据类型时,并没有明确规定其使用的字节序。这是因为在数据库层面,字节序通常是由底层操作系统和硬件处理的。而Oracle作为一个跨平台的数据库系统,会根据不同的操作系统和硬件平台自动选择合适的字节序。
一般来说,大端序在网络传输中更常见,而小端序在现代个人计算机中更为普遍。但无论是使用大端序还是小端序,Oracle都能够正确地将二进制数据存储和检索出来。
总结起来,Oracle中的BLOB数据类型的字节序取决于底层操作系统和硬件平台,并且Oracle能够适应不同的字节序进行数据存储和检索。这意味着在使用Oracle BLOB时,开发人员不需要手动考虑字节序的问题,只需要关注数据的正确存储和处理即可。
