H2 Database Engine Review

I like that it's open source, so you can customize your own version of MySQL for use in an enterprise environment without paying licensing fees to Oracle or another vendor who may not be as interested about providing support beyond what they charge per year (or more). It also has some nice features such as being able to have multiple users connect at once with their respective credentials - this allows us to do things quickly when we need them done! The only thing i dislike right now is having

It's easy to use, it has very good performance in terms of speed for queries that I need, and its free! The only downside about this product would be if you have multiple users sharing one machine (e.g., web server) or even more than 1 user using same computer at once. If your app needs lots of concurrent connections with DBs like MySQL/Postgresql then go ahead and give hsqldb another try since they support connection pooling which will help tremendously when compared against other products…
