Couchbase Server

Couchbase is the modern database for enterprise applications.

Couchbase Server is an open source, distributed, JSON document database. It exposes a scale-out, key-value store with managed cache for sub-millisecond data operations, purpose-built indexers for efficient queries, and a powerful query engine for executing SQL-like queries. For mobile and Internet of Things environments Couchbase also runs natively on-device and manages synchronization to the server.

try {
  final QueryResult result = cluster.query("SELECT * FROM `travel-sample`.inventory.airline LIMIT 100",

  for (JsonObject row : result.rowsAsObject()) {
    System.out.println("Found row: " + row);

  System.out.println("Reported execution time: " + result.metaData().metrics().get().executionTime());
} catch (CouchbaseException ex) {
