Is the code 64-bit ready ? What was limiting the scalability to 1 million rows rather than say 100 million ?
The OS refused to map more than 2GB into my address space.
- This seems a core library that boost should have. Do you
plan to submit it ?
I hadn't honestly considered it. Isn't this functionality covered by Shmem anyway? Persist is completely free - so Shmem could make use of it. I would certainly be happy to change the license from LGPL to Boost.
I have to study shmem but I think the persistent STL bits are more suited as the base library for other database libraries like RML and not as part of
a shared memory library.
It's only an organizational issue. My feeling is that if the persistent containers are developed by people working on database issues it will get more focus on performance and be more suited for real-world solutions.
On the other hand, one would expect that the implementors of a memory-mapped library would not be completely oblivious to performance. There are many tricky OS-related issues with shared/mapped memory, that is a project in itself. The answer lies in benchmarking different implementations. Regards, Calum
