Eclipse Vert.x 3.9.2 released!

We are extremely pleased to announce that the Eclipse Vert.x version 3.9.2 has been released.

Among all bug fixes you can find in 3.9.2 this enhancement

Meet the Reactive DB2 Client

The Reactive SQL Client family gets a new child with an implementation contributed by our fellow maintainer Andy Guibert.

Using DB2 client is as straightforward as its elder sibblings:

DB2ConnectOptions connectOptions = new DB2ConnectOptions()

// Create the client pool
DB2Pool client = DB2Pool.pool(connectOptions, poolOptions);

// A simple query
  .query("SELECT * FROM users WHERE id='julien'")
  .execute(ar -> {
  if (ar.succeeded()) {
    RowSet<Row> result = ar.result();
    System.out.println("Got " + result.size() + " rows ");
  } else {
    System.out.println("Failure: " + ar.cause().getMessage());

  // Now close the pool

Reactive MySQL Client domain socket support

The MySQL reactive Client can now connect using domain sockets.

// Connect Options
// Socket file name /var/run/mysqld/mysqld.sock
MySQLConnectOptions connectOptions = new MySQLConnectOptions()

// Create the pooled client
MySQLPool client = MySQLPool.pool(connectOptions, new PoolOptions().setMaxSize(5));
