Influx db java client batch does not write to DB

I am trying to write points to influxDB using their Java client.
Batch is important to me.

If I use the influxDB.enableBatch with influxDB.write(Point) no data is inserted.
If I use the BatchPoints and influxDB.write(batchPoints) - data is inserted successfully.

Both code samples are taken from: https://github.com/influxdata/influxdb-java/tree/influxdb-java-2.7

InfluxDB influxDB = InfluxDBFactory.connect(influxUrl, influxUser, influxPassword);
influxDB.setDatabase(dbName);
influxDB.setRetentionPolicy("autogen");

// Flush every 2000 Points, at least every 100ms
influxDB.enableBatch(2000, 100, TimeUnit.MILLISECONDS);
influxDB.write(Point.measurement("cpu")
.time(System.currentTimeMillis(), TimeUnit.MILLISECONDS)
.addField("idle", 90L)
.addField("user", 9L)
.addField("system", 1L)
.build());

Query query = new Query("SELECT idle FROM cpu", dbName);
QueryResult result = influxDB.query(query);

Returns nothing.

BatchPoints batchPoints = BatchPoints.database(dbName).tag("async", "true").build();
Point point1 = Point
.measurement("cpu")
.tag("atag", "test")
.addField("idle", 90L)
.addField("usertime", 9L)
.addField("system", 1L)
.build();
batchPoints.point(point1);
influxDB.write(batchPoints);
Query query = new Query("SELECT * FROM cpu ", dbName);
QueryResult result = influxDB.query(query);

This returns data successfully.

As mentioned, I need the first way to function.
How can I achieve that?

versions:
influxdb-1.3.6
influxdb-java:2.7

Thanks

Commencez par le chemin enableBatch du client Java et reproduisez le premier exemple de code avec InfluxDB 1.3.6, puis comparez son comportement avec celui de l’exemple fonctionnel de BatchPoints. Vérifiez la correction en confirmant qu’un point écrit via enableBatch est renvoyé par la requête fournie après l’intervalle de vidage du batch.
