Is there any interest in providing relational containers in Boost? Are there any features/improvements you can suggest for RML?
You could compare the library with sqlite.
Completely different. Most database engines are controlled via text strings, and require parsing and data transformation. This cuts all that out using C++ templates, and is therefore way faster. It's a container.
Oh, sorry my request was not formulated clearly enough. I wanted to see how rml performs compared to sqlite in a benchmark. Sqlite is currently a nice and fast solution if you do not need a remote database. Rml could be an even better solution, if you do not require a text sql interface, provided that there are table types available in rml, which work without being fully loaded to memory.
Furthermore you could implement a table that can be stored in a file, and used wihout reading all records into memory.
I think the memory-mapped file route would be the most profitable, it would probably already work.
Interesting, could you give a short overview, how it could already work. Regards, Andreas
