Is it possible to create an in memory only concurrent datastore
application?

Yes you can create a memory only database using CDS.

Ron,

I did have a look at that page but when I do a

"env->open(env_home_dir, DB_SYSTEM_MEM , 0 )" the error message says
"Failed to open env: : No such file or directory"...

so I used flags "DB_SYSTEM_MEM | DB_CREATE" and it says "Failed to open
env: : Invalid argument" ...

and lastly I used "DB_CREATE | DB_INIT_CDB | DB_INIT_MPOOL |
DB_SYSTEM_MEM" and it says "Failed to open env: : Invalid argument"

I want the CDS with no on disk file storage, I hope the above
illustrates the issue
thanks
