r2dbc-h2 does not guarantee compatibility except against the version of H2 found in the build file. Because various parts of H2 are blocking, like file and network access, the only non-blocking assurances are in the layers above H2. Nevertheless, r2dbc-h2 is a great way to warm up to the usage of R2DBC with a small footprint.

Since we added H2 as a dependency, Spring Boot knows that in this project we will be connecting to the H2 database, so it auto-configures H2-related properties like the database URL, username, password, etc: If we look at the datasource.url property, the name of the schema is testdb and is an in-memory database (refered to as "mem").

Parameters. url - a database url of the form jdbc:subprotocol:subname. Returns. This method returns connections to the URL. Exception. SQLException will be thrown, if database access occurs or url is null.. SQLTimeoutException will be thrown, when the timeout value specified by the setLoginTimeout method has been exceeded and tried to cancel the current database connection attempt.

The default database instance is in-memory by default and uses the jdbc:h2:mem:kuradb URL. Most persistent. A persistent database instance can be created using the jdbc:h2:file:, where is a non-empty string that represents the database path. If no URL parameters are supplied the database will enable the transaction log by default.
