Opinions, Expertise, Passion.

Better late then never, this week I finally have the chance to catch up on some overdue posts. At the first MySQL Camp I made a list of memorable Quotes, see Day 1, Day 2, Day 3. I didn’t get as much chance as last time, however here are some pearls of the recent MySQL Camp II.

“I walked in of the street for the free food. I’m here for the free education” - Adrian.

“I’m his boss, I’m here to make sure he’s really here, and not playing hooky.”

“Mashups, collating the worse bugs from multiple API’s all in one place” - OSCON badge

“Compiles 114,000 combinations of MySQL that we are interested in.” Sandro - Skoll Project — You mean to say there are are combinations your not interested in.

“Ok, people this is the second site were are going to crash today. You have heard you have been slash dotted, now you have been camped.”

Jay turning down the lights, to the whole auditorm, not just the stage. “That won’t work. My paper isn’t backlit.” — Andrew

Jeremy: “It’s a porn site.”
Sheeri: “technocation.com it’s not a porn site, I work for a porn site.”

Jeremy: “You don’t realize how many Google properties you use, google reader was down, google search was down, google maps was down.”
Sheeri: “I had to use Yahoo maps, I feel so dirty.”

Jay: “How many people are interested in a tour of the MySQL Source Code.”
Jeremy II: “It is a guided tour, isn’t it.”

“I can’t remember if was the cold, hot or luke warm”. — Bob, In the backup talk.

“How many environments have it. They all have the presumption of it.”

The Taso Dump

I’ve gotto go, my time has come. (maintenance window needed)
Could not get a lock. (table lock)
I needed a blocker to ensure a single thread. (–single-transaction)

Finally, got a lock. (–lock-tables)
Need to ensure no transactions lost.
Dump, Dump, Dump. (mysqldump)

I’m having flow problems.
Was the buffer to small? (key_buffer_size)
Was it the query cache? (query_cache)
My Dirty Pages may be too high? (innodb_max_dirty_pages_pct)
Or was it just Too Many Connections? (max_connections)
But it was just waiting on the flush (flush tables with read lock)

Time passes, Time Passes. No output yet.
Is it network saturation?
Is it IO bound?
Do I need a better flushing method (innodb_flush_method)
No, it was just the lag? (Seconds_behind_master)

Dump is complete (unlock tables)
Now it’s time to Purge (purge logs)

If there is an attempt to restore.
The backup would be empty.
Blackhole would be found as the cause.
In the end, all transactions lost!

If you weren’t at Friday dinner after MySQL Camp II you missed it.
It’s not meant to be MySQL grammar correct, it’s just some random words we were throwing around.

MySQL Camp II is complete. A small group of about 18 had post dinner at Tiny Thai in New York City. Some elected to drive from Brooklyn, they arrived at least 30 minutes after those of us that the subway.

I have a lot of notes to write, if ever the time permits. For now, the following few that joined for drinks are below. I know other people took photos of the camp, for a change I actually took none. If you want to add a link in comments of photos from the camp that would be great.

Other sizes here

We have started MySQL Camp II. The first session is Introductions.

I didn’t catch all the employers, but here is part of the list of attendees at the Introduction section. Great to see multiple people from many places including ESPN, priceline.com, Proven Scaling, Solid Tech - sponsors of Dorsal Source, ForSaleByOwner. fontshop.com, 9Mmedia, CafeMom, JP Morgan, Upoc, ClubMom, Stock Photo Finder, AmieStreet,LogicWorks, Skoll - Distributed Continuous QA , AOL, Minggl, Minggl New Test Site, Visibone. Others include OnlineBuddies.com, NT Snort User Group, DreamweaverNY User Group, A law firm. As well as a few people from MySQL.

Many people mentioned having an Oracle background, or working with Oracle now, at least 6 people that heard me speak at “MySQL DBABootcamp for the Oracle DBA” last week.

There were a lot of MySQL Beginners here which was really great.

And now we are onto the discussion of the sessions.

Well readers, your either here or your not. MySQL Camp II starts today in Brooklyn, New York, at Polytechnic University. Last night’s pre drinks meetup in NYC went well, but today it’s brass tacks time. View Larger Map

For those of you not able to make it, IRC@Freenode #mysql-camp will be the place to hang out to hear what’s happening. If your not at the camp, please identify yourself. Be sure to also check out the Camp Web Site MySQL Camp II for the plans for today and tomorrow.

For those of you not here, MySQL Camp III is already in planning.
