Re: Store C++ STL Vector in MySQL Database
I concur with the "blobs" answer - which means your requirements do not appear to warrant a database and the overhead it brings.
Convert the .csv data into a set of flat binary files.
Somehow you know where to find the data in the .csv files now.
Code that knowledge & logic and you can leverage the OS for caching and pre-fetching of your files.
If the data access is random then with a x64 OS you can memory-map the files into your program's virtual memory space and the OS uses the page-fault mechanism to load your data and I know Windows will anticipate what you will read next and will pre-fetch, I would presume Linux has a similar feature with a sufficiently modern kernel.
If access is linear then aio/asynchronous-IO will allow you to prefetch chunks for processing.
