Which embedded database capable of 100 million records has an efficient C or C++ API

Question

I\'m looking for a cross-platform database engine that can handle databases up hundreds of millions of records without severe degradation in query performance. It needs to h

Answer 1

One option could be Firebird. It offers both a server based product, as well as an embedded product.

It is also open source and there are a large number of providers for all types of languages.

Answer 2

Many good solutions (such as SQLite) have been mentioned. Let me add two, since you don't require SQL:

• HamsterDB fast, simple to use, can store arbitrary binary data. No provision for shared databases.
• Glib HashTable module seems quite interesting too and is very common so you won't risk going into a dead end. On the other end, I'm not sure there is and easy way to store the database on the disk, it's mostly for in-memory stuff

I've tested both on multi-million records projects.

Answer 3

There used to be a product called b-trieve but I'm not sure if source code was included. I think it has been discontinued. The only database engine I know of with an ISAM orientation is c-tree.

Answer 4

SQLite would meet those criteria, except for the eventual shared file scenario in the future (and actually it could probably do that to if the network file system implements file locks correctly).

Answer 5

As you are familiar with Fairtree, then you are probably also familiar with Raima RDM.

It went open source a few years ago, then dbstar claimed that they had somehow acquired the copyright. This seems debatable though. From reading the original Raima license, this does not seem possible. Of course it is possible to stay with the original code release. It is rather rare, but I have a copy archived away.
