Getting started

// Connection to MySQL DB
Connection connection = 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.

If you want information specific to the drivers, check the [PostgreSQL README](postgresql-async/README.md) and the [MySQL README](mysql-async/README.md).

You can view the project's change log [here](CHANGELOG.md).

DateTime:

Version 1.x always returns JodaTime when dealing with date types and not the java.util.Date class nor jdk-8 dates.
Version 2.x works with java 8 DateTime objects (java.time.LocalDateTime and such).
This post can help with migration.
