FirebirdSQL vs. H2 Database Engine vs. Milvus

It is able to handle simultaneous connections when using the embedded software version. It is well suited for organizations looking for standalone servers that can handle high data volumes and still perform well and which is also cost-effective database management system especially when they are working on a low budget.

For running application tests it's well suited. H2 [Database Engine] can replace the real-world database solution for them easily and removes the requirement to set up a a separate database instance just for running unit tests. For using in actual production application one needs to consider scale. H2 is suitable if application runs in single instance and database is located in same machine as a file where that application runs. This means the application shouldn't have a large user base. However it's easy to switch to an actual MySQL instance if the need arises, it's most likely only a configuration change and doesn't require new code.

• Performance is really fast.
• It is portable and easy to take back ups.
• Its open n source and free.

Incentivized

• Can run as an in-memory database.
• Simple and quick to get started with, and is light weight (only 2MB).
• SQL compliant so it compatible with most relational databases.

Incentivized

• Documentation.
• No GUI tool to view data.
• Slow via remote access.

• There's a warning in official FAQ "Is it Reliable?"-section which makes it seem like H2 is not yet a mature product.
• If raw SQL queries are used there maybe be differences between MySQL & H2. ORM library should be used.
• Support seems to be community-based only.

Because it is free and usually zero maintenance. Just the issue of more difficult format updates in the future lower the rating a bit.

Usability has improved by unifying the architecture. The only thing's missing out of the box is a simple GUI DB tool for viewing DB contents and maybe running some SQL queries.

This is an open source project. It provides a fair amount of free documentation and I think forums somewhere...

Even somebody just starting to use RDBMS himself should get it working quickly, at least if he's got a GUI tool and some SQL knowledge.

Incentivized

Because it is having Open Source License and easy to deploy on windows and linux environment

While both can run as an in-memory database, H2 Database Engine was just so much easier for us to use since we primarily use the Java stack and H2 Database Engine is also built with Java.

• Cost effective saving us from paid relational database.
• Community support.
• Efficiency in handling simultaneous connections.

Incentivized

• Doesn't take time from developers, once it's configs are set up for testing it works in everyone's development environments
• Easy to integrate in application, no need to setup separate database software, no maintenance
• No need to deal with infrastructure related issues/costs - database runs in same machine as the application that uses it.
