Hi.

 I've tried to update the driver used in my Maven project from 2.1.214 to 2.2.220, and now it gives me some error:

"The write format 2 is smaller than the supported format 3 [2.2.220/5]".

Seems that I have to upgrade the database as well? How do I upgrade it to be able to use the latest driver, as long as this one seems to be no more warnings in it!

Best regards,

Vali

[Andreas Reichel]

Greetings!

You could use the H2 Migration Tool https://manticore-projects.com/H2MigrationTool/index.html

H2 last release (220): after insert /delete command :

In runtime, after a few inserts and deletions to the database version 2.2.220, our database was damaged, and we observe such a picture on several servers.
Before that, we used version 2.1.214 for over 4 months without problem.
The database version 220 was created from 0 and data was entered into it by sql commands.

Hello, 

I have also this problem using the same H2 version - get a corrupted database.
Do you have any solution or fix? 

Because without any fix that version is unusable for me.

Thanks,

  Jürgen

Hi, Jurgen and TheRaywell, Andrei has released h2-2.2.222 yesterday evening for public. I had a same error like You and now my code works OK without any error. So You can try 2.2.222 version and send the result to the appropriate email thread https://groups.google.com/g/h2-database/c/yCIcidC0piA. Regards, Stepan

Hello Everybody,

A new version 2.2.222 of H2 is available at http://www.h2database.com
(you may have to click 'Refresh').

This is a patch release, and AFAIK there are no incompatibilities with
on-disk format of v.2.2.220, so hopefully it can be used as drop in
replacement for 2.2.220 (and only 2.2.220!).

It will be available in Maven repository shortly.

For details, see the 'Change Log' at
http://www.h2database.com/html/changelog.html

P.S. If you reply to this message please use a different subject.

Have fun,
Andrei Tokar

Thank you very much.

Just in case: We have amended H2MigrationTool for support of H2 2.2.222 already.

Thanks for the fix version 2.2.222.
Don't know if it will work for me, because I run with that revision into a performance problem.
One of my unit tests runs now extremely long and it seems that much memory get allocated.
Can't send you the complete code but I isolate it to the SQL statements and looks like:

CREATE TABLE IF NOT EXISTS A (number VARCHAR(128) not NULL, intent INT not NULL, objID VARCHAR(30) not NULL, objType SMALLINT  not NULL, PRIMARY KEY (number,intent,objID,objType));
CREATE INDEX IF NOT EXISTS A_IDX ON A(objType,objID,intent);
CREATE INDEX IF NOT EXISTS A_type_IDX ON A (objType);

for (int loop = 0, number = 0; loop < 300; ++loop){
  DROP TABLE IF EXISTS B;
  CREATE TABLE IF NOT EXISTS B (number VARCHAR(128) not NULL, intent INT not NULL, objID VARCHAR(30) not NULL, objType SMALLINT  not NULL, PRIMARY KEY (number,intent,objID,objType));
  CREATE INDEX IF NOT EXISTS B_IDX ON B(objType,objID,intent);

  for (int i = 0; i < 100; ++i) {
    ++number;
    MERGE INTO B (number,intent,objID,objType) VALUES (Integer.toString(number),1, Integer.toString(number), 1)
  }
 
  DELETE FROM A T WHERE EXISTS (SELECT NULL from A S WHERE T.objID=S.objID AND T.objType=S.objType AND T.intent=S.intent AND T.number<>S.number)
  MERGE INTO A T USING (SELECT * FROM B) AS S ON T.objID=S.objID AND T.objType=S.objType AND T.intent=S.intent AND T.number=S.number WHEN NOT MATCHED THEN INSERT (objID, objType, number, intent) VALUES (S.objID, S.objType, S.number, S.intent);
  DROP TABLE B CASCADE
}

If run with the previous versions 1.4, 2.1 and 2.2.220 it's finished after some seconds.
With the 2.2.222 it takes longer with each loop; don't finish after some minutes.

Please take a look; thanks.

Thanks,

  Jürgen

[Andreas Reichel]

Greetings Juergen.

Unfortunately I can't reproduce your concern after implementing your test in the quickest and dirtiest way, with lots of overhead.

It ran through in 1 minute and I did not see any slowdown while iterating:

> Task :ETLBox:H2PerformanceTest.main()

Aug 29, 2023 6:13:20 PM com.manticore.etl.custom.H2PerformanceTest main

INFO: loop = 0

Aug 29, 2023 6:13:20 PM com.manticore.etl.custom.H2PerformanceTest main

INFO: loop = 1

Aug 29, 2023 6:13:20 PM com.manticore.etl.custom.H2PerformanceTest main

INFO: loop = 2

....

Aug 29, 2023 6:14:07 PM com.manticore.etl.custom.H2PerformanceTest main

INFO: loop = 296

Aug 29, 2023 6:14:07 PM com.manticore.etl.custom.H2PerformanceTest main

INFO: loop = 297

Aug 29, 2023 6:14:07 PM com.manticore.etl.custom.H2PerformanceTest main

INFO: loop = 298

Aug 29, 2023 6:14:08 PM com.manticore.etl.custom.H2PerformanceTest main

INFO: loop = 299

BUILD SUCCESSFUL in 1m 13s

What exactly means "after some seconds" vs. "after some minutes"?

Can you elaborate on the details please?

Best regards
Andreas

H2 Team,

do you have any facility in place for running such performance tests across various versions of H2 and comparing the outcome?

Something like:

1) load driver

2) run various test scripts 

3) write performance measures for this driver version as per script

4) unload driver

and repeat over all provided drivers.

if not, would you like to accept such a basic test performance test suite?

Best regards

Andreas

Sure, sounds like a useful tool.

[Andreas Reichel]

Greetings!

I have run your test through all H2 versions and have not been able to see any material performance deviation:

Those are very rough estimates based on System.currentTimeMillis() without engaging the JMH benachmarking tool.

I am still working on a generic Performance Test Framework, which can read simply Test Case Scripts like the one attached.

In the meantime, please elaborate on your concern since I can't really confirm it so far.

Best regards

Hi Andrei,

As far as I got it, the version 2.2.222 is an important patch to version 2.2.220, but it is still not available in the Maven repository. So please add this version to the repository.

Best and many thanks in advance
Manfred

[Andrei Tokar]

Manfred,
It was just uploaded to repository by Thomas Müeller .

Jürgen, Andreas,
I was able to replicate your performance problem, and filed a test case in H2 issue tracker.

[Jürgen Pingel]

Hello Andreas, 

sadly I haven't earlier time to prepare the data and run with different versions. But today I had a little bit time for, so here my results.
In all 2 test runs same code - but only using the different H2 versions; running in a MAC system.

Any ideas?

Thanks,

  Jürgen

H2 2.2.222 has a known regression: it doesn't perform automatic calculation of statistics.

You need to run the ANALYZE command by yourself. In real-words applications it can be enough to call its once after insertion of enough amount of data, in unit tests you may need to call it in every test that inserts many rows.
