# Reactive Relational Database Connectivity Client (R2DBC)
This project is an exploration of what a Java API for relational database access with [Reactive Streams][rs] might look like.  It uses [Project Reactor][pr].  It uses [Jdbi][jd] as an inspiration.

## Examples
A quick example of configuration and execution would look like:

```java
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);
```
