What is H2?

Introducing H2, a Java SQL database tailored for effective data management. In its embedded mode, applications can directly connect to the database within the same Java Virtual Machine (JVM) via JDBC, which is the fastest and most straightforward method of connection. Nevertheless, this configuration has a limitation: it restricts database access to a single virtual machine and class loader at any given time. Similar to other operation modes, it supports both persistent and in-memory databases, allowing for an unlimited number of simultaneous database accesses or open connections. Conversely, the mixed mode merges characteristics of both embedded and server modes, where the first application connecting to the database functions in embedded mode, while concurrently initiating a server for other applications in separate processes or virtual machines to access the same data at the same time. This combination facilitates local connections to benefit from the rapid speed associated with embedded mode, though remote connections might encounter minor latency. Ultimately, H2 stands out as a versatile and powerful solution capable of meeting diverse database requirements, making it an appealing choice for developers.
