Hi, Jeff. Actually, slow query logging series (3 videos) serves as Part 2 of MySQL Performance Tuning, even though I should have stated it clearly: 1. kzread.info/dash/bejne/oKN60JSsl7TPfto.html 2. kzread.info/dash/bejne/e4Kj2Muoj6nbhLg.html 3. kzread.info/dash/bejne/mGqay9uYlLm_qNo.html

Thank you, Shailesh! I'm really happy about it.

seems the author of this video is very busy or changed the line. Thank you so much for this highly knowledgeable video ever on MySQL

Excellent

Thanks that was great :)

Thank you much for sharing your knowledged. I find it very valuable content. Please let me ask. Minute 43.52 shows commands pager grep seq and show engine innodb status\G select sleep (60); the results on my end are not the same. Can you explain are they both sepparate commands or are all in one line.

Thank you so much

Puikus video!

Everyone is highly appreciating this video. I don't even know what is said there! 😞

So glad that I found this video, thanks for sharing BTW, I've downloaded the ebook and seems that it is got encrypted or something else when I open it. What should I do to fix this ?

Sorry, my bad. I can read the ebook now. Thanks

Great Video!! There are few other settings which we are tweaking on the server like sort_buffer_size, max_heap_table_size, max_connections. Are they not important? We changed them on recommendation by mysql tuner script.

Hi, Ashish. Thanks! All settings are important, it's just that some are importanter than others ;) Re the ones you mentioned: - sort_buffer_size - only increase per query (you can test it with specific query and you'll see if it helps) - max_heap_table_size (and tmp_table_size) - would be fairly high on the list too. watch Created_tmp_disk_tables status variable to understand if it could help to increase it, but note that sometimes tmp tables are created on disk becasuse tmp tables don't support dynamic columns (text/blob) - max_connections - not really related to performance. mysql can have high number of idle connections at virtually no cost (tens of thousands). but if you need to change it, definitely do that. Hope that helps.

Thanks, 👌

innodb_buffer_pool_size really give a big difference if configure properly. My program keep having timeout issues when not set correctly. When I changed from default 80MB to 2GB, the program never have SQL timeout issue.

Please publish more videos :)

Hey nice tutorial. Great help. I recently saw mysql 8.0 is available. Whats your recommendation on using that?

MySQL 8.0 will be a great release. It's not GA yet. Here's a few things I'm personally looking forward to (but there will be more, I'm sure) - www.speedemy.com/new-in-mysql-8-0-dr/

Hi, can the same config be used for mysql 8 ?

Is there Part 2 of this video?

fantastic, can you do a similar video for mysql8 :)

your website is down. can you share alternative link.

can you share your PPT slides please

Great Content. Thank you. But the links are not working.

I read at Percona's blog high innodb_io_capacity values can be bad for SSD. Also Letsencrypt server on 24 M.2 enterprise SSD still has innodb_io_capacity set to like 1000 to avoid frequent flushing. They say SSD will wear much faster with values set to 50-75% of actual IOPS. So maybe we should be careful using high innodb_io_capacity without good reason.

Guys, Anyone have the my.cnf files. It seems the website is no longer active. Please, share the file with me.

Should it be query_cache_type =OFF or query_cache_type=0
