如何在Cassandra中存储无符号整数？ [英] How do I store unsigned integers in Cassandra?

问题描述

我正在通过Datastax驱动程序在Cassandra中存储一些数据，并且我需要存储无符号的16位和32位整数。对于无符号的16位整数，我可以轻松地将它们存储为有符号的32位整数，并根据需要进行强制转换。但是，对于无符号的64位整数，我很茫然。我可以将它们存储为字符串并进行解析，也可以将它们存储为字节数组。我可以将它们存储为64位有符号整数，并进行从64位无符号整数转换为64位无符号整数所需的位操作。

I am storing some data in Cassandra via the Datastax driver, and I have the need to store unsigned 16-bit and 32-bit integers. For unsigned 16-bit integers, I can easily store them as signed 32-bit integers and cast them as needed. For unsigned 64-bit integers, however, I am at a loss. I can store them as strings and parse them, or I can store them as byte arrays. I could store them as 64-bit signed integers and do the bit manipulation required to convert from and to 64-bit unsigned integers.

推荐答案

您可以使用Cassandra的 varint ，在C＃驱动程序中表示为 BigInteger 。

You can use Cassandra's varint, represented in the C# Driver as BigInteger.

您可以显式转换从 BigInteger 到 ushort 和 ulong 。
