Reactive Relational Database Connectivity Client (Archived)

This project is an exploration of what a Java API for relational database access with Reactive Streams might look like. It uses Project Reactor. It uses Jdbi as an inspiration.

Examples

A quick example of configuration and execution would look like:

PostgresqlConnectionConfiguration configuration = PostgresqlConnectionConfiguration.builder()
    .host("<host>")
    .database("<database>")
    .username("<username>")
    .password("<password>")
    .build();

R2dbc r2dbc = new R2dbc(new PostgresqlConnectionFactory(configuration));

r2dbc.inTransaction(handle ->
    handle.execute("INSERT INTO test VALUES ($1)", 100))

    .thenMany(r2dbc.inTransaction(handle ->
        handle.select("SELECT value FROM test")
            .mapResult(result -> result.map((row, rowMetadata) -> row.get("value", Integer.class)))))

    .subscribe(System.out::println);
