### Question:
InfluxDbClient { public boolean writeMetricsAsync(final String content) { try { ASYNC_EXECUTOR.execute(new ReqTask(content)); return true; } catch (Throwable t) { Logger.error("InfluxDbClient.writeMetricsAsync(): t=" + t.getMessage(), t); } return false; } InfluxDbClient(Builder builder); boolean createDatabase(); boolean writeMetricsAsync(final String content);  }### Answer:
@Test public void testWrite() throws InterruptedException { boolean write = influxDbClient.writeMetricsAsync( "cpu_load_short,host=server01,region=us-west value=0.64 1434055562000000000\n" + "cpu_load_short,host=server02,region=us-west value=0.96 1434055562000000000"); System.out.println(write); TimeUnit.SECONDS.sleep(3); }
