Re: My test 15 - External DB performance and ZEOS 7.2-beta

Thanks for sharing the numbers.
No test with direct SynDBODBC.pas unit? I guess it may be a little lower than ZDBC/Zeos.

It is worth saying that AnyDAC/FireDAC is changing the default SQlite3 configuration to synchoff/exclusive mode.

Re: My test 15 - External DB performance and ZEOS 7.2-beta

@Junior
No, lower numbers = slower.
I guess that ODBC is slower than Zeos/ZDBC, since ZDBC has direct access to the database driver.

This is what we observed on our side.

Re: My test 15 - External DB performance and ZEOS 7.2-beta

@All

since Zeos7.3 i made a little code join with/for the synopse-project.
There is a new define $USE_SYNCOMMONS available which than directly uses the SynCommons.TJSONWriter.
You can either add it to your compiler options or just uncommend the define in Zeos.inc.

This define than finally brings actual best performance for ZDBC + mORMot. The SynCommons.TJSONWriter is pretty nice optimized, because of this i decided to skip a Zeos own approch and just used the one of mORMot.  Now Zeos is able to return JSONs. So both projects do benefit from the latest patches.

As you've noticed Michal (miab3) also did test the two new Zeos-ODBC Drivers. I wrote them to make the leap according MSSQL + Zeos and NON Windows plattforms and becouse i wanted to know what brings best MSSQL access rates ... OleDB is the winner in this domain.

Numbers are talking, guys ... from !my! POV there are no performance (are there otheres for mORMot? ) advantages using FireDac or UniDac as well. Remembering the first results of 7.1 series Zeos access rates where between FireDac/UniDac. Now most code is optimized and completely refactored.

Arnaud and me worked hand in hand to get best performance running for his framework and Zeos it's selves too of course!

Note i'm not ready with the complete refactoring. Just most parts of ZCore up to ZDbc have been reworked from ground up. Actually my Zeos coding time is rare comparing my previous activities but 7.2-stable will come soon. (For those who do not trust in the beta attribute ... It's up to Mark,Michal,Jan and me just to tag 7.2 as stable candidate! We'll do that if latest fix is older than 3 weeks.

Missing points:
I've noticed there are adtional options in mORMot. Such like limit the lob sizes or just ignore them.
As a work around i propose to use the JSONWriter.TSQLFieldBits/Fields for composing the json-contents and just ignore those fields. Any other ideas?

@miab3

thanks for attaching the results! I was out of time to setup the whole database batery!

Sadly i see you miss a Zeos OleDB-driver results, or am i wrong? Could you test the OleDB driver + MSSQL too?
In addition could you enable the $USE_SYNCOMMONS define please?

@AB

i was waiting a while before anouncing the define or new drivers. Some final regressions have been fixed. (And beause of lack of time i've tested each protocol @all)
===> THANK's for updating your documantations! This is a great advertinsing for Zeos.


Cheers, Michael

@Michael,

I added to the previous ZEOS 7.3 OleDB (at the moment without $USE_SYNCOMMONS)

Re: My test 15 - External DB performance and ZEOS 7.2-beta

@ab, @EgonHugeist,


Enable USE_SYNCOMMONS

mORMot: [dcc32 Fatal Error] SynDBZEOS.pas(138): F2051 Unit ZDbcCache was compiled with a different version of SynCommons.TTextWriter.AddNoJSONEscapeUTF8

ZEOS: "ZDbc contains implicit unit(s) SynCommons, SynLZ"

It gets a cross between a libraries.
It's probably not a good solution?

Michal is from Poland so it should be CP1251

On my side the code compiles and runs fine with my whole compiler battery. No issues to see, just better performance results (:

Re: My test 15 - External DB performance and ZEOS 7.2-beta

I just downloaded ZEOS Lib 7.3 from SourceForge, integrated with mORMot and compiles under XE8,  every thing seems OK.  I am trying to connect to MSSQL by chosing the connecting parameters from the Update Connection Setting of SynDBExplorerClasses. What should be specified for the Server input ? I tried the "IP", "IP,1433", and "IP:1433"  as the Server parameter without success. So what should be specified for the Server and Database parameters?

Thanks in advance.

Re: My test 15 - External DB performance and ZEOS 7.2-beta

Thanks for testing with the latest version of the framework!

I didn't expect any performance change, but we may have introduced some regressions.

Thank you. @miab3.

My backend MSSQL is MSSQL2016.  I tried the above strings, and It seems not work.

Then I compiled the whole ZEOS package V7.3-alpha. By using the TZConnection, TZQuery components, I found that the value for parameter Url of function TZDriverManager.GetConnectionWithParams(const Url: string; Info: TStrings):  IZConnection;
  is a quite long string: zdbc:OleDB://127.0.0.1:1433/Provider=SQLOLEDB.1'#9'Password=XXXX'#9'Persist Security Info=True'#9'User ID=YYYY'#9'Initial Catalog=ZZZZ'#9'Data Source=127.0.0.1?username=UUUU;password=PPPP'

So I give the following string in UI of SynDBExplore as: OleDB://127.0.0.1:1433/Provider=SQLOLEDB.1, and found that when SynDBZeos call
GetConnectionWithParams, the Url is just about the same.
    zdbc:OleDB://127.0.0.1:1433/Provider=SQLOLEDB.1?username=UUUU;password=PPPP;controls_cp=CP_UTF8

The TZConnection, TZQuery works in Win64. But when combined zeos with mORMot, the Zeos raised a lot of exceptions such as EZSQLException OLEDB Error 80040E14 and Can't found the datatype CLOB. I use RawUTF8 datatype for UTF-8 Strings. 

What is wrong for my usage of SynDBZeos and Zeos?
