带有influxdb-java的批点被覆盖，除非强制唯一时间？

Question

InfluxDB connection = InfluxDBFactory.connect(server, client);
connection.enableBatch(100,10,TimeUnit.MILLISECONDS);
connection.setDatabase(database);
BatchPoints batchPoints = BatchPoints.database(database).build();

long currTime = System.currentTimeMillis()*1000000;
double[] data1 = getInfluxData();
for (int i=someInt; i < data1.length; i++){
    if (i % someInt == 0){
        double[] data2 = processData(data1, i-someInt, i);
        for (int j=0; j < data2.length; j++){
            Point p = Point.measurement(someTable)
                .time(currTime+i+j, TimeUnit.NANOSECONDS)   //Line A (j < someInt)
                .tag("someTag", "someTagValue")
                .addField("someField", data2[j])
                .build();
            batchPoints.point(p)
        }
}
connection.write(batchPoints);
connection.disableBatch();
connection.close();

Answer 1

在InfluxDB中，所有具有相同标记值和时间戳的点，即使具有不同的字段值，也被认为是重复的。因此这些数据点会被无人值守地覆盖。这与InfluxDB设计一致。

Is it a limitation of influx that only one point can exist with the same tags and timestamp?

是的，这是故意的。

If a collision does occur, does the old one get overwritten?

是的，它是静默覆盖的。
