Getting started

// Connection to MySQL DB
Connection connection = new MySQLConnectionBuilder.createConnectionPool(
               "jdbc:mysql://$host:$port/$database?user=$username&password=$password");
     
// Connection to PostgreSQL DB    
Connection connection = PostgreSQLConnectionBuilder.createConnectionPool(
               "jdbc:postgresql://$host:$port/$database?user=$username&password=$password");

// Execute query
CompletableFuture<QueryResult> future = connection.sendPreparedStatement("select * from table");
// work with result ...
// Close the connection pool
connection.disconnect().get()

See a full example at jasync-mysql-example and jasync-postgresql-example.

Overview

This project is a port of mauricio/postgresql-async to Kotlin.
Why? Because the original lib is not maintained anymore, We use it in ob1k, and would like to remove the Scala dependency in ob1k.

This project always returns JodaTime when dealing with date types and not the java.util.Date class. (We plan to move to jdk-8 dates).

If you want information specific to the drivers, check the PostgreSQL README and the MySQL README.

You can view the project's change log here.

Is it used in production on large scale?

The graph above is from only couple of services using it. Y-Axis is # of queries per minute.

There is also a TechEmpower test using ktor and jasync-sql.
