Please note this only affects data cache (tuple storage) and not metadata cache.
请注意这只会影响数据缓存（元组存储）且没有元数据缓存。
The ROW data type can be equated to a table definition: it defines multiple columns that are grouped together into a tuple.
ROW数据类型可以等同于一个表定义：它定义可以组成一个元组的多个列。
In this case, you iterate through the contents of the recv aggregate, sum the packet lengths for each tuple (device name, PID, and process name), then emit this data.
在本例中，您将遍历recv聚合的内容、为每个元组(设备名、PID和进程名)相加包的长度，然后发出该数据。

Tuples are very useful for containing defined elements and describing different complex data structures, and Erlang allows you to set and get values in a tuple explicitly (see Listing 15).
元组对于包含定义的元素和描述各种复杂数据结构非常有用。Erlang允许显式地设置和获取元组中的值(参见清单15)。
The key isn't restricted to being an integer; it can be any nonmutable data type, including an integer, float, tuple, or string.
键并不限制为整数；它可以是任何不易变的数据类型，包括integer、float、tuple或string。
And just like a tuple, a list can hold different types of data (or different types of objects). This is what I mean by a heterogeneous mutable sequence.
就像tuple一样，list也可以持有不同类型的数据(或不同类型的对象)，这就是我所说的异构的可变序列。
