DH,

Since inMemory storage engine is part of Enterprise, the source code for it
is not available publicly.

You might want to ask the second question on the mongodb-dev Google group
which is for questions about developing MongoDB itself (which this
definitely qualifies for).

I have a couple questions:

1) I downloaded the Enterprise version but only binaries are available.
The source tree download version does not have the In-Memory code.  Is the
In-Memory source code available for public anywhere?

2) I have a special memory-like block device and want to implement a
simple storage engine (no caching needed) using direct I/O to the block
device, would implementing the Storage Engine API be the best way to go or
is there a better way to leverage an existing implementation (i.e. by
changing file operations open/read/write to do that)?

Thanks,
DH
