即将用户写的PySpark程序”映射”到JVM中,例如,用户在PySpark中实例化一个Python的SparkContext对象,最终会在JVM中实例化Scala的SparkContext对象;在Executor端,则不需要借助Py4j,因为Executor端运行的Task逻辑是由Driver发过来的,那是序列化后的字节码,虽然里面可能包含有用户定义的Python函数或Lambda表达式,Py4j并不能实现...

When using BSON in an application that also uses ActiveSupport, the ActiveSupport-related code must be explicitly required: require 'bson' require 'bson/active_support'BSON Serialization Getting a Ruby object's raw BSON representation is done by calling to_bson on the Ruby object, which will ...
TAB_SIZE tag can be used to set the number of spaces in a tab. Doxygen # usesthis value to replace tabs by spaces in code fragments. # Minimumvalue: 1, maximum value: 16, default value: 4. TAB = 4 # Thistag can be used to specify a number of aliases that act as ...
This kind of driver is extremely flexible, since it requires no code installed on the client and a single driver can actually provide access to multiple databases.You can think of the application server as a JDBC "proxy," meaning that it makes calls for the client application. As a result,...
