Does influxdb-java has limitation for the # of select queries in one query() call?

Bắt đầu bằng cách tái hiện năm câu lệnh thông qua InfluxDB.query() với cả hai khoảng thời gian, sau đó so sánh QueryResult được trả về với các lỗi của máy chủ và máy khách, nếu có. Kiểm tra xem các kết quả bị thiếu bắt nguồn từ máy khách Java hay từ cơ chế xử lý multi-statement của InfluxDB; công việc được xem là hoàn tất khi xác định được thành phần giới hạn và ghi lại một lời giải thích có thể tái hiện.

Question

My influxdb database stores the data from May 2nd to May 5th, and the query string is as below, which contains 5 select:

SELECT metricsA FROM measurementA WHERE time >= '2023-05-02T10:10:30.78+08:00' AND time < '2023-05-20T08:20:30.78+08:00' AND ((uniqId = 'cadd3c08082f07740c459d4366b91002' AND sign=~/.*/) OR (uniqId = 'c0c0250e096735acc6b6dc341b47504a' AND sign=~/1.1|1.2/)) GROUP BY uniqId,sign tz('Etc/GMT-8');
SELECT metricsB FROM measurementB WHERE time >= '2023-05-02T10:10:30.78+08:00' AND time < '2023-05-20T08:20:30.78+08:00' AND ((uniqId = 'cadd3c08082f07740c459d4366b91002' AND sign=~/.*/) OR (uniqId = 'c0c0250e096735acc6b6dc341b47504a' AND sign=~/1.1|1.2/)) GROUP BY uniqId,sign tz('Etc/GMT-8');
SELECT metricsC,metricsD FROM measurementC WHERE time >= '2023-05-02T10:10:30.78+08:00' AND time < '2023-05-20T08:20:30.78+08:00' AND ((uniqId = 'cadd3c08082f07740c459d4366b91002' AND sign=~/.*/) OR (uniqId = 'c0c0250e096735acc6b6dc341b47504a' AND sign=~/1.1|1.2/)) GROUP BY uniqId,sign tz('Etc/GMT-8');
SELECT metricsE FROM measurementD WHERE time >= '2023-05-02T10:10:30.78+08:00' AND time < '2023-05-20T08:20:30.78+08:00' AND ((uniqId = 'cadd3c08082f07740c459d4366b91002') OR (uniqId = 'c0c0250e096735acc6b6dc341b47504a')) GROUP BY uniqId tz('Etc/GMT-8');
SELECT metricsF FROM measurementE WHERE time >= '2023-05-02T10:10:30.78+08:00' AND time < '2023-05-20T08:20:30.78+08:00' AND ((uniqId = 'cadd3c08082f07740c459d4366b91002' AND sign=~/.*/) OR (uniqId = 'c0c0250e096735acc6b6dc341b47504a' AND sign=~/1.1|1.2/)) GROUP BY uniqId,sign tz('Etc/GMT-8');

I'm calling InfluxDB.query() to execute it, but only the first 3 select query returns QueryResult. The Json format of QueryResult is:

"result":[
    {
        "series": [
                    {
                        "name": "measurementA",
                        "tags": {
                            "sign": "1.1",
                            "uniqId": "c0c0250e096735acc6b6dc341b47504a",
                            "IP": "4.4.4.4"
                        },
                        "columns": [
                            "time",
                            "PSUIn"
                        ],
                        "values": [
                            [
                                "2023-05-03T08:04:00+08:00",
                                900.0
                            ],
                            ...
                        ]
                    }
          ]
    },
    {...},
    {...}
]

When I execute each select query seperately, they can all return QueryResults. And there is more, which is when I narrowed down the time range to { 2023-05-02T10:10:30.78+08:00 ---- 2023-05-04T10:10:30.78+08:00 } instead of { 2023-05-02T10:10:30.78+08:00 ---- 2023-05-20T08:20:30.78+08:00 }, it works just fine and gives all the results for 5 queries.

I had no clue why this happened. Is there any constrants for the number of select query in one query() call?
