Jencks: Innodb repetable reads postgresql repeatable reads, they are defined and implemented differently
Erle: Salle: i just check and say.
Heximer: NoOova: If that matters the ANSI standard requires only SERIALIZABLE isolation level. All other levels are up to the vendors discretion to define and implement
Heximer: NoOova: Hence nothing unusual there
Veto: Salle: nope. you wrong
Primer: I just launched “repair table mytable”, how can I run it in background ?
Hainsey: Salle: mysql see not phantom rows. it see all commited rows!
Meir: So UPDATE test SET id = 100 WHERE id = 5 will update unvisible row!
Gregoreski: But in standart there are no ‘FOR UPDATE / FOR SHARE’ features =
Martinov: Hey guys, i would like to get 5 random users and their latest 5 comments as in nested JSON. Is it possible to limit comment join to 5?
Calder: I just launched “repair table mytable”, but this will take long time, how can I keep this task in background please ?
Swartzman: Serdem420: http://jan.kneschke.de/projects/mysql/groupwise-max/ http://dev.mysql.com/doc/refman/5.6/en/example-maximum-column-group-row.html
Leubner: Jkavalik, That example is not my case i think.
Imbrogno: In the example it sums the datapopulation and reduce to a single field.
Shear: What i am after is look like son. One user, one comments filedarray and five top comments.
Loeb: Group concat can be used with HEXto make valid json but limiting is still a very big problem.
Chicon: Substring is can be used but nah!
Conninghan: Can I just disconnect from mysql shell without stop current process running ?
Borden: Can I “push” the current process to background ?
Manocchia: U can always open a send connection :
Heximer: Or third, fourth . up to max_connections
Heximer: Xat: You can for example run mysql via screen and detach it
Toala: Salle: yes but the process is already running
Stangle: Xat, you can try using something like retty to attach it to a screen
Serratos: I’ll try it Stangle ;
Boers: I have a large database 235 GB? that updates a variety of rows constantly, would I be correct to think it’ll need high disk throughput?
Helmsing: Cluelessperson: probably right, yes.
Night: It should be updating a huge number of rows nearly all of them once a minute or so. Indexing probably won’t be much help
Heximer: Cluelessperson: Better redesign that database
Heximer: Cluelessperson: I doubt with modern hardware you can update 235GB every minute
Heximer: Cluelessperson: Are you talking about single table?
Sideman: Salle, That may be a large over exageration. We’re basically monitoring machines in the field.
Dellaripa: Hi All, Quick question, for MySQL 5.6 what is the default Row size in total bytes before all queries are using Temp Table on disks, instead of memory?
Maycumber: Every machine I install workbench on, workbench crashes
Kravs: Also if my table has 1 TEXT column does it mean all my queries on this table will be using Temp Tables on disk or only when I select the TEXT column? Thanks
Reindeau: Cluelessperson: workbench ****s =
Mehaffy: How to clear errors from mysql error log
Kanno: Silent_Ninja: have you reviewed https://dev.mysql.com/doc/refman/5.6/en/internal-temporary-tables.html
Schons: Just got MySQL Workbench to work on AWS RDS MySQL 5.6 last week :
Shelvy: Hi Kanno, Thanks I think I read it but want to confirm, not 100% certain even after reading the info. I’ll try reading again. thanks
Kanno: Silent_Ninja: there are server configuration settings noted at that page that determine when a temp table will be written to disk
Rhoda: But by default if I have TEXT column in the Table does, it hit temp to disk automatically, even if I don’t select the TEXT column in th query?
