Recommend a light, open-source, in-memory DBMS based on C++?

Question

I'd like to have an in-memory databaes, that is

I hope the speed is fast. Function-wise, I'm only looking into basic CRUD operations, stored procedure support would be a bonus.

Pls kindly recommend.

There is no such thing as a light-weight DBMS - in any language. A DBMS is a large-to-huge, and complex, software system. I would also not entertain the hope of maintaining the code of a DBMS yourself - that's not going to happen. Having said that, if you are interested on working on DBMSes, maybe we should talk (it's my field of research). ... So, essentially, you need to change your requirements or settle for a "no" answer. — einpoklum, Apr 6, 2017 at 20:58
Agreed. OP does not want to consider mainting the code (why would he?). So, the answer is probably sqlite.org/inmemorydb.html — Mawg says reinstate Monica, Apr 7, 2017 at 10:01
@Mawg clarify: I do intend to maintain the code. That's why I'm looking into minimum code base and minimum function — athos, Apr 7, 2017 at 10:21

The closes that I can think is SQLite: https://www.sqlite.org/index.html

But it has not all the feature you need.

The main point was "in memory". For which, see sqlite.org/inmemorydb.html

@athos It is written in C, not C++.

@athos would that be a problem for you?

See my comment 4 above this one - sqlite.org/inmemorydb.html But, are you ok with is being coded in C, or do you insist on C++ ?
