List the minimal actions needed to reproduce the behaviour.

Timestamps queried from InfluxDB 3 Core via JDBC Driver are inconsistent with those inserted.
To be honest, I'm not sure whether this issue should be placed on https://github.com/influxdata/influxdb or https://github.com/apache/arrow-java. But considering that no one has ever written unit tests for InfluxDB 3 Core on https://github.com/apache/arrow-java, I think I should confirm it on the InfluxDB side first.
I created a minimal unit test at https://github.com/linghengqian/influxdb-3-core-jdbc-test/blob/master/src/test/java/io/github/linghengqian/TimeDifferenceTest.java. To execute it, just install SDKMAN! and Docker CE in advance, then,

sdk install java 21.0.6-ms
git clone [email protected]:linghengqian/influxdb-3-core-jdbc-test.git
cd ./influxdb-3-core-jdbc-test/
sdk use java 21.0.6-ms
./mvnw -T 1C -Dtest=TimeDifferenceTest clean test

    }
    private void queryDataByInfluxDbClient(InfluxDBClient client) {
        try (Stream<PointValues> stream = client.queryPoints("select time,location,value from home order by time desc limit 10",

            List<PointValues> list = stream.toList();
            assertThat(list.size(), is(1));
            PointValues p = list.getFirst();
            assertThat(p.getField("value", Double.class), is(30.01));
            assertThat(p.getTag("location"), is("London"));
            assertThat(p.getTimestamp(), is(NanosecondConverter.convert(magicTime, WritePrecision.NS)));
        }
    }
    private void queryDataByJdbcDriver() throws SQLException {
        HikariConfig hikariConfig = new HikariConfig();
        hikariConfig.setJdbcUrl("jdbc:arrow-flight-sql://" + container.getHost() + ":" + container.getMappedPort(8181) + "/?useEncryption=0&database=mydb");
        try (HikariDataSource hikariDataSource = new HikariDataSource(hikariConfig);
             Connection connection = hikariDataSource.getConnection()) {
            ResultSet resultSet = connection.createStatement().executeQuery("select time,location,value from home order by time desc limit 10");
            assertThat(resultSet.next(), is(true));
            assertThat(resultSet.getString("location"), is("London"));
            assertThat(resultSet.getString("value"), is("30.01"));
            assertThat(Timestamp.from(magicTime).getTime(), is(magicTime.toEpochMilli()));
            assertThat(resultSet.getString("time"), notNullValue());
            assertThat(resultSet.getTimestamp("time").getTime(), is(magicTime.toEpochMilli()));
        }
    }
}

Obviously, there is no concept of ZoneId or Offset for java.time.Instant, which is a fixed point on the continuous timeline. The timestamp of the fixed time is inserted through the InfluxDB Client, and then the same timestamp can be obtained by executing SQL to the InfluxDB Client. However, executing the same SQL through the Flight JDBC Driver will obtain a timestamp that is inconsistent with the original one. That is, this assertion will fail.

assertThat(resultSet.getTimestamp("time").getTime(), is(magicTime.toEpochMilli()));

Some early investigation came from The documentation or JavaDoc of InfluxDBClient should document the existence of NanosecondConverter InfluxCommunity/influxdb3-java#222 .

Expected behaviour:
Describe what you expected to happen.

Timestamps queried from InfluxDB 3 Core via the JDBC driver are consistent with the inserted timestamps.

Actual behaviour:
Describe What actually happened.

Timestamps queried from InfluxDB 3 Core via JDBC Driver are inconsistent with those inserted.

Environment info:

Please provide the command you used to build the project, including any RUSTFLAGS.
- It seems that this is not needed, I use the Docker Image quay.io/influxdb/influxdb3-core:911ba92ab4133e75fe2a420e16ed9cb4cf32196f directly in my unit test.
System info: Run uname -srm or similar and copy the output here (we want to know your OS, architecture etc).
- Linux 5.15.167.4-microsoft-standard-WSL2 x86_64
If you're running IOx in a containerised environment then details about that would be helpful.

$ docker --version
Docker version 27.5.1, build 9f9e405

Other relevant environment details: disk info, hardware setup etc.
- Considering that I execute unit tests under WSL, it’s hard to say there’s anything special about this. However, my WSL time zone environment is set to Asia/Shanghai.

Config:
Copy any non-default config values here or attach the full config as a gist or file.

It doesn't seem necessary.

Logs:
Include snippet of errors in logs or stack traces here.
Sometimes you can get useful information by running the program with the RUST_BACKTRACE=full environment variable.
Finally, the IOx server has a -vv for verbose logging.

The unit test will dynamically create a Docker container, so I think I only need to provide the log for the unit test.

@linghengqian - 👋 thanks for the detailed write-up!

How are you certain that the row in the query result that you are asserting against is the row that was written in the previous step of the unit test?

The discrepancy in the timestamps is quite large (1738986704151 - 1738929104151 = 57600000), and from what I can tell you are writing to / reading from a influxdb3 server that is not running in isolation in the test. So, the query may be producing a result set from writes done in other test runs or otherwise.

Perhaps you could try writing som unique value into a tag or field column, using a UUID, or something that is unique to the test run, and then include a WHERE clause in your query to ensure that the result you are asserting on is the row that was written in.

linghengqian · 2025-02-10T15:47:42Z

How are you certain that the row in the query result that you are asserting against is the row that was written in the previous step of the unit test?

I had to refer to the documentation of testcontainers-java https://java.testcontainers.org/ and I have made sure that each unit test creates a separate container. See https://github.com/linghengqian/influxdb-3-core-jdbc-test/blob/master/src/test/java/io/github/linghengqian/TimeDifferenceTest.java .

private final Instant magicTime = Instant.now().minusSeconds(10);

@Container
private final GenericContainer<?> container = new GenericContainer<>("quay.io/influxdb/influxdb3-core:911ba92ab4133e75fe2a420e16ed9cb4cf32196f")
            .withCommand("serve --node-id local01 --object-store file --data-dir /home/influxdb3/.influxdb3")
            .withExposedPorts(8181);

what I can tell you are writing to / reading from a influxdb3 server that is not running in isolation in the test. So, the query may be producing a result set from writes done in other test runs or otherwise.

I honestly don't understand this statement. I am not sharing the same Influxdb 3 Core instance between unit tests. Each unit test is creating a separate Docker container of Influxdb 3 Core instance. What does this mean?

Ah, if that is the case, then I apologize, I misunderstood the code / description and did not realize each test is running an isolated container.

So, the --data-dir /home/influxdb3/.influxdb3 is on the container and therefore only lives for the lifetime of the test.

You might be able to try adding some more verbose logs to the server output with your serve command on the container, e.g., using the -v argument

serve --node-id local01 [...] -v

And then, if possible, share the log output here. There may be some clues there.

I updated the unit test at linghengqian/influxdb-3-core-jdbc-test@3425a66 and the log of the container is as follows.

Of course, I know that the default time zone of the Docker Image of influxdb 3 core is UTC. But I still don't understand why there is such a difference.

mgattozzi · 2025-02-10T18:11:51Z

@linghengqian One thing I notice is that you have comparisons in milliseconds, but the server stores timestamps in nanoseconds, especially if the write to the DB is not in nanoseconds. We try to automatically figure out what precision you sent the timestamp in as. There might be some discrepancy there.

If you want to be really sure that they do not share state between invocations I would use the arguments serve --node-id local01 --object-store memory so that they don't accidentally use the same files on disk. If you want to store them on disk still then randomizing the node-id so they don't overlap is essential

If you want to be really sure that they do not share state between invocations I would use the arguments serve --node-id local01 --object-store memory so that they don't accidentally use the same files on disk.

I don't understand why this would result in the same data files on disk being used, my unit tests don't actually mount any volumes on the host, /home/influxdb3/.influxdb3 is actually a path inside the container.
I have switched the unit test to use memory as object storage in linghengqian/influxdb-3-core-jdbc-test@536a562 , but the timestamp obtained from the query is still wrong.

@linghengqian a couple more things that you might be able to try:

use -vv for DEBUG logging
try an EXPLAIN ANALYZE query, i.e., EXPLAIN ANALYZE <original query> and capture the output of that

Otherwise, the timestamp that you are getting is consistently 16 hours off of the expectation. Maybe there are some UTC to local conversions happening that are responsible for the offset. I'm not 100% sure of that, since you aren't doing any casting of the query time value, so what is written in should be what is queried out without the need for casting.

FWIW influxdb3 assumes the written time is UTC, and stores as UTC.

One thing I noticed was that the log line for the WAL flush:

2025-02-11T03:33:27.008726Z  INFO influxdb3_wal::object_store: flushing WAL buffer to object store host="local01" n_ops=2 min_timestamp_ns=1739244795878445031 max_timestamp_ns=1739244806716134380 wal_file_number=1

Specifically, min_timestamp_ns=1739244795878445031 is the same as the expected value in your test:

Expected: is <1739244795878L>
     but: was <1739187195878L>

It may be helpful to look at the actual query result to see what raw timestamps are there.

linghengqian · 2025-02-12T06:01:01Z

I have updated the unit tests to use -vv and execute EXPLAIN ANALYZE at linghengqian/influxdb-3-core-jdbc-test@041050b . I also removed query assertions on the influxdb3 java client that were causing the log to become more verbose. It's hard to say that I know anything special about these logs.
Does this mean that the bug is somewhere inside apache arrow ?

It's hard to say that I know anything special about these logs.

I agree, the logs don't reveal much to me either.

It may be helpful to look at the actual query result to see what raw timestamps are there.

Would it be possible for you to display the raw result set? I am not as familiar with the Java Client/Flight SQL implementation, so I don't know the easiest way to do this, but if you could output the full query result, it would help to know:

How many rows are returned
What the raw timestamps are to rule out any time zone conversions that might be done implicitly by the InfluxDB/SQL clients and to see if they are actually different from what was written in

Would it be possible for you to display the raw result set? I am not as familiar with the Java Client/Flight SQL implementation, so I don't know the easiest way to do this, but if you could output the full query result, it would help to know:

I thought about it and found that without a third-party library, the original data set that prints EXPLAIN ANALYZE select time,location,value from home order by time desc limit 10 needs to be processed manually. I made the output of EXPLAIN ANALYZE similar to CSV in linghengqian/influxdb-3-core-jdbc-test@0542a18 .

How many rows are returned

You can see from the explain plan that there is one row outputted:

SortExec: TopK(fetch=10), expr=[time@0 DESC], preserve_partitioning=[false], metrics=[output_rows=1, elapsed_compute=1.319786ms, row_replacements=1]
                                                                                      ^^^^^^^^^^^^^

So that's good.

Can you do the same to output the regular query result? i.e., without EXPLAN ANALYZE, to see the raw timestamp.

linghengqian · 2025-02-13T14:55:50Z

I will say that the default timezone for the influxdb 3 core docker container is UTC, while my WSL instance is set to Asia/Shanghai in East 8, which is a 16 hour difference which is a bit weird. Refer to my changes at linghengqian/influxdb-3-core-jdbc-test@438e7d0 .

hiltontj · 2025-02-13T16:45:53Z

I will say that the default timezone for the influxdb 3 core docker container is UTC, while my WSL instance is set to Asia/Shanghai in East 8, which is a 16 hour difference which is a bit weird

I suspect the issue is related to time-zone conversion.

I wonder if you were to try some other methods to convert the time column value in your assertions, would you get the correct result.

You may know the options better than I, but instead of using getTime in this line:

assertThat(resultSet.getTimestamp("time").getTime(), is(magicTime.toEpochMilli()));

Perhaps try toInstant or some other method on Timestamp to get the value for assertion?

linghengqian · 2025-02-14T06:26:08Z

I simplified the logic of the unit test a bit to simply expose the assertions. Located at linghengqian/influxdb-3-core-jdbc-test@34be9a8 .
The time obtained from the Apache Arrow Flight JDBC Driver is 16 hours different from the time originally inserted.

assertThat(resultSet.getTimestamp("time").toInstant(), is(magicTime));

Or I guess you wanted something like this logic, but that's not possible.

assertThat(resultSet.getObject("time", Instant.class), is(magicTime));

According to [JDBC] Timezone improvements for the JDBC driver apache/arrow-java#463 , it seems that there are problems with the design of arrow spec, which causes arrow-java to be unable to implement related processing normally. But I personally am not a C++ expert...
