Azure表存储位数据类型

Question

I am architecting a table for my Azure Table Storage based app, and I need it to have 100 "columns" with bit or boolean datatypes.

I can obviously store int flags as my column datatype, but since there are 100 per table entry, I would like to make the entries (aka, "rows") as small as possible. If I use int flags, my entry size will be 100 bytes , but if I'm able to use a bit datatype, then it is obviously 8 times smaller.

Booleans seem like they should work in theory, but I just read ( here ) that Booleans take a full byte in memory.

Is there a way to have a datatype that is truly 1 bit in size and able to be stored in Azure Table Storage ?

Thanks!

The Windows Azure Storage REST API documentation provides the definitive specification of what can be done with Azure Tables. The data model and supported datatypes are documented here .

Since individual columns aren't indexed and result in a table scan when queried, could you not use some other storage mechanism for the data. For example, you could store the data in a byte[] property in a Table entity. Indeed, if the only data you are storing in the entity are these bits then you could even use blobs instead.
