Cold Case "DISABLE/ENABLE or REPLACE=UPDATE on Triggers"

The fact that MySQL is not supporting at his best triggers and Store Procedure, is something we all know quite well.

Because that, we normally do use them with caution, but the other day I was working on a simple action on a customer site, and I face something that I did not recognize immediately, because I was starting from a wrong assumption.

Let me describe the case. A customer needs to perform regular export of his data, and reload of it on a different site. To do that we put up an external procedure using "select into outfile" and "Load DATA in FILE".

Nothing special here.
Given we know what we were doing we also set the REPLACE or IGNORE keyword as manual: "The REPLACE and IGNORE keywords control handling of input rows that duplicate existing rows on unique key";

We disable UNIQUE and FOREIGN KEY checks as well, finally no replication or binary logging is in place, so no concern that side.

Then we run the import and got an error message :"ERROR 1062 (23000): Duplicate entry '1' for key 'PRIMARY'".
This time the message error was quite clear, and I should not have problem in recognize the issue, right? It is a primary key duplication, BUT and here there is the need of a BIG BUT, I am using the REPLACE keyword because I want my inserts from file overwrite whatever is in the table.

Given I have being use that for years without any issue, I (me fool) did not recognize at the first shot the rot reason of the error.

This is because in my mind the keyword "REPLACE" had a special meaning, that for obvious reasons it does not have in MySQL.

To simplify my life here I have replicate the issue using the test dataset Sakila, so if you want to have fun try it downloading the schema from MySQL site.


So what I have done:

  • Load schema/data
  • Take an export in CSV
  • take info about triggers constrains and so on:

It Is MyISAM because the full text (next time we will use Innodb full text ;) ), it use "film_id", as primary key.


At this point I think you should have already get why I was a fool, and where was my misunderstanding.

I was thinking that GIVEN I have REPLACE in primary key in the LOAD DATA IN FILE statement, MySQL was able to propagate this condition also to relate tables.

So when I saw the error I was a little bit ... annoyed.

I did a quick check on the FILM_TEXT table:

And yes data is there and at this point I must assume that this is the cause of the error.

So Marco stop dreaming about REPLACE cascade action and do something.

Cool, let me DISABLE the trigger such that I can reload the table on FILM without worries.

But oops I CANNOT disable a trigger, and more... what if the data I am inserting is the same for Primary key but not for the text, and I need to replace data in the DESCRIPTION fields?

Well I cannot do it without modifying the trigger itself.

So at the end I have to do something in the triggers like so instead of using

 

1
2
3
4
5
6

So at the end I have TO do something IN the triggers LIKE so instead of USING
DELIMITER ;;
CREATE TRIGGER `ins_film` AFTER INSERT ON `film` FOR EACH ROW BEGIN
    INSERT INTO film_text (film_id, title, description)
        VALUES (new.film_id, new.title, new.description);
END;;

 

We need to use

7
8

10
11

    INSERT INTO film_text (film_id, title, description)
        VALUES (new.film_id, new.title, new.description)  ON DUPLICATE KEY UPDATE film_id=new.film_id;
  END;;

    ->   END;;  
Query OK, 0 rows affected (0.11 sec)
 

 

Which obviously will work fine:

1
2
3
4

 mysql> LOAD DATA INFILE '/tmp/sakila_film.csv' REPLACE INTO TABLE sakila.film  FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\"' LINES TERMINATED BY '\r\n';
Query OK, 1000 rows affected (0.57 sec)
Records: 1000  Deleted: 0  Skipped: 0  Warnings: 0
 

 

Problem solve, and all fine.
Really? Not really!

I have few comments here and I met two annoying issue during my exercise.

 

The first one is that I am still not able to disable the triggers, this is a feature request pending from 2005 http://bugs.mysql.com/bug.php?id=14661, we can discuss the best way to implement it, but not the fact that it is a NEEDED feature.

 

Second if I use REPLACE on LOAD DATA INFILE, I could expect a "Cascade" behaviour of the REPLACE action, at least when I involve the primary key in the Trigger.
That actually should be quite simple, like FIRING the UPDATE trigger instead the INSERT, not rocket science, no need to check what you are doing in the trigger, REPLACE=UPDATE in Trigger action.

In term of suggestion to the others, I can only say ... "REVIEW the triggers code to include the possible case of duplicate inserts", but I don't like it.
I think that we should go for a more elegant way to run it, then modify the trigger code, which was a simple operation here, but that could not be always the case.


Is this a critical issue? No we can stay as we did so far.
Is this something easy to solve? I think so.

Would make any sense to change it as I describe? I think so.
More I would like to say that I don't understand how we can have the option to disable FOREIGN key in place and STILL not have it for Triggers.

That is for me another annoying Cold Case, also if takes me few minutes to fix it!

In the lasts weeks, I choose to stay silent, to try to see and read other people blogs with a new eye. I was trying to go in depth of any single article, reading investigating and double-checking.

There were a lot of news and things going on, not all new and not all really interesting for me, but at the end, enough to le me say that I had spent many nights up reading and studying, instead leading ahead my own projects.

But what was surprise me as well, was that at the end what is very often interesting as a NEW feature or cool coming solution, it is not so interesting in the day by day work.

More what happens is sometime, or I should say too often, the new things that are cool development, are built on the rubble left behind.

Too often we have to still deal with annoying OLD bugs, or feature requests that are "by the facto" standard in almost all decent Database platforms.

Just in the last page (as for the time of writing) of Planet MySQL, I can see mention of the Microsecond issue from Chris Calendar, the way how MySQL handle temporary tables in "A More Perfect UNION " and last but not least my annoying lack of trigger DISABLE/ENABLE function.

So at the end I found myself looking to what I start to call "Cold Case" in my mind. I also star to thought "how I can help"? Well not forgetting them, and instead write and write again about them every time I will find, hoping to be able to propose also some works around, whenever possible.

This is why I have open a series of "Cold Case".

I also invite you all to do not forget and do not leave them behind. Write about your Cold Case and let us push for having them solve once for all.

So what? nothing new ... from MySQL AB time.

at http://blogs.oracle.com/MySQL/entry/new_commercial_extensions_for_mysql

I saw it and I smile, hey I am happy to see that seriously!!


What I saw there were feature really Enterprise oriented AND really good for them as well, I though "GOOD STUFF", her what Rob report:

MySQL Enterprise Scalability

  • Thread Pool

MySQL Enterprise High Availability

  • Oracle VM Template for MySQL Enterprise Edition
  • Windows Clustering for MySQL Enterprise Edition

MySQL Enterprise Security

  • External Authentication for PAM
  • External Authentication for Windows

This is in line with what was discussed and discussed and discussed and discussed in MYSQL AB from 2006.

What do you think it would have being happen if unless being bought by SUN MySQL would have gone public?

Do you remember we did not have "Falcon" because it was not really scaling right, and we did invest a lot of money there,
so what will have MySQL done to recover some money and to be able to find an alternative solution?

MySQL will have done exactly the same because it makes a lot of sense, it is a logical path to follow in a open market.
What stops MySQL was not the fact that people in MySQL were good and now the Oracle guys are bad.
What stop it was the SUN acquisition, and the fact that SUN was so far away from MySQL  that they don't really understand what would be good to go for, Period.

Oracle is just following not only his internal model, but something that was already up in the air from quite long.
MySQL needs to be Enterprise oriented, and in order to do that needs to have spacial features that are not available for the community version.

What I am really whatching is not if Oracle ask money for Enterprise feature, but that Oracle will not leave the community version behind.
I don't want to see MYSQL GA becoming a "B" series product, what I am concern is to have the same core feature, and to have in the enterprise ONLY the added ones specifically focus for the Enterprise customers.

I am exited to try the new features, and I will have the chance to do it downloading the MySQL enterprise trial.

I strongly recommend to read Giuseppe blog (http://datacharmer.blogspot.com/2011/09/welcome-mysql-commercial-extensions.html),

What will be tomorrow I cannot say, but so far so good, Go MySQL and (I will never imagine I would say that) go Oracle, good Job!

As usual my 2cent in supporting the cause.

This post is not technical!

 

Who knows me, knows that I am not a nasty person.

I try to be polite and politically correct, and that has being a problem for me several times, because it pays only in long term.

 

But to day I need to talk about MySQL-Proxy so I can say something not pleasant for someone.

sakila_proxy_256x298

I have found myself in trouble several time because MySQL-Proxy for stability reasons and performance issues, but a part from that it normally works as expected.
Is really up to you and how you uses normally if you will get in trouble or not.

But ... hey MySQL-Proxy is an ALPHA product, oh my!!

 

It is an ALPHA not even BETA or RC, more reading the documentation TODAY:
"This documentation covers MySQL Proxy 0.8.0.
Warning

MySQL Proxy is currently an Alpha release and should not be used within production environments."

 

Honestly I have being mention MySQL -Proxy several times to customer but I always say to them, IT IS ALPHA, if you want I will install it,
I will configure and write for you special LUA scripts, BUT you must sign a paper that state you take the responsibility of installing an ALPHA product in production.

Normally the 90% of customers stops to go ahead, and try to find a different solution.

 

Too bad because MySQL-Proxy if correctly maintained could be an incredible tool, and ouch!! I discover this bug http://bugs.mysql.com/bug.php?id=61474.

Well you know is an ALPHA product so, I say to myself too bad, we should not expect a fast resolution.
We wait for a while then nothing really "serious" happened there, no fix, nothing, so we decide to drop it from the architecture.
The customer was not happy and neither I.

 

But I take note of it, and given I KNOW that MySQL Enterprise monitor use MySQL-Proxy I decide to dedicate some time to check, if this is still the case or not.

 

Today, I had a discussion with my 9 years Son, and to relax a little I put myself in front of some fun ... working with MySQL, yes I still enjoy it.

So I take out the Enterprise installation I did install it and then test it.

As expected MySQL-Proxy is still there, and documentations states:
"Using the MySQL Proxy functionality built into MySQL Enterprise Agent. This is the method offered and supported since MySQL Enterprise Monitor 2.0."

All good then, we have the possibility to add our own monitor or to use the default one provided by Oracle.

Hey wait a minute, is this a GA product?
No it is an Enterprise Product!

So why the MySQL Enterprise Monitor is using as default solution for an important functionality as the Slow Query Review an ALPHA product?

This sounds really odd to me.


Given I think no one will be happy to pay money for an ALPHA product, that has also issue with the latest MySQL versions, and given I think that lawyers in Oracle knows quite well their works.
I come to the conclusion that the MySQL-Proxy included in the Enterprise version is different from the one available.

Or at least I hope that for all the ones that are paying solid money for MySQL Enterprise Manager.

 

In any case, it is very sad that good and valuable work done in the past years by Jan Kneschke, and others like GiusePPe Maxia, is left behind damaging the community.

MySQL-Proxy is still the only solution for many stupid issues left behind in the MySQL programming, like user audit.

 

I recently had to implement a detailed audit of the actions done by Administrator on a MySQL instance.
The only very good and manageable solution was at the end the use of MySQL-Proxy, I will describe the work done in another post.

 

What I want to stress and reiterate here is:question-mark

  • IF MySQL-Proxy is so good to be in the MySQL Enterprise Monitor, that we assume it should be the top of stability, why then is still declared ALPHA??
  • IF MySQL-Proxy in Enterprise is a different product, then WHY it is not state in a clear way somewhere?
  • Finally WHY MySQL-Proxy is not correctly fixed and align with the latest MySQL products?


Simple questions that comes to my mind, I am not expecting an answer but may be some paying customers,
will have the same doubts I have, and it could be that given they pay they will get a real answer back from Oracle.

In that case please let us know.


Great MySQL to ALL!!!

I am reading the announcement about the Percona MySQL event in place of the O'Reilly.

sakila_speaker_offWhat I see and what I feel  is that the whole MySQL community, including Oracle, Percona, SkySQL,MariaDB and any other company doing business with MySQL have lost a good opportunity (so far).

For many years we have seen and hear comments about having this event more focus on users, and less bound to a single company. Now what? We will have a single company promoting the event. I don't care if it is done by Percona instead Oracle or SkySQL, actually I like all of them and I knew personally almost all of them as well.

What I care/like is to have this event NOT limited to a single company.

There was an attempt to have it organized in a different way (see Giuseppe  and Sheeri  comments), but then what?

I remember a long time ago (1983) when I was in Delhi and we have to run from the waiting room to the aeroplane in order to take a sit, that because the lack of coordination at the airport.
Are we in the same situation today?
The one that will move faster will get the place and the other will need to find a place after?

As a user I don't see that as a good thing, lacking in coordination, not be able to find a way to agree on how to do things, is never good.
As someone coming from MySQL I don't like it at all, where is the spirit of cooperation we had in MySQL is it completely gone?

After the MySQL diaspora, I have seen many time personal interest (and company interest) take over the common benefit, but at the end what happened is that we have now a potentially stronger MySQL community.
This because we need to see all of us (Oracle, Percona, SkySQL, MariaDB and any other related like Pythian where I am currently working) as competitor but also as part of the same “community”, we can compete for crumbs or we can compete for excellence, to be better. Wondering how many others community have such huge opportunity.

So I am really wonder what happened here? Are all of us so weak that we are not be able to organize an event as the MySQL conference?

I think that, as already happened in the past, all the actors would like to see this event happening as an OPEN and Independent event, focus on users and ... on business as well.

Said that, is Percona acting bad? No I don't think so, they are moving ahead, period. It is in their DNA, acting, do things.

Are them not following their own previous statements? Is too early to say that, but what I see here is also an incitation to all others to move on, and act.

What I really hope is to do not have in the next feature a SkyMySQL MySQL event, a MariaDB MySQL event and so on.

What I hope is to see all of us converging and helping each other in having this event as a common event and not as a single company.
Percona did the first move, but this doesn't prevent all others to join and have it to become a MySQL Community event. It will be great to recognize to Percona the role of initiators, but it would also be great to see Percona able to modify his position in respect to the event, from single company event to community open event.

As always I am a dreamer, and my dream here is that $$$ are less relevant than the great work we can do all together.
Despite the fact that doing it as single company will awaken less interest (also in $$$) then doing it as community event.

Remain one big question mark ... who will be in? Who is really ready to start putting effort and money to have a successful  MySQL global event?

Will be nice to see statements of real commitment coming in from all actors.


Great MySQL to every one.
