According to this http://dev.mysql.com/doc/refman/5.5/en/binary-log-mixed.html
Page, if you set transaction-isolation=READ-COMMITTED, you cannot use Statement-based Binary Logging, but have to use Row-based or Mixed (binlog_format = ROW|MIXED).

Since binlog_format = STATEMENT is the the default, you have to change it also, if you also change the transaction-isolation.

Since (I assume) Row-based logging is a performance hit, isn’t it better to stick to the default transaction-isolation (REPEATABLE-READ)?

Hi there,
First thanks a lot for the info regarding the innodb.

I am actually contemplating converting some of my tables which are currently set as myisam to innodb.

what kind of table should i set to run innodb engine, does it matter or not at all.

I am a bit new to that but if i can ask, do you have any info regarding the transactions deadlock, what can i do to prevent it?

My database will be habdling loads of users and users content, i will surely use a master/slave but would this run into problems as their will be writes queries going on from different users??

Thanks again and hope i make sense:).

Nice post, but the basic MySQL tuning for innodb you need its to set the database ( innodb_file_format ) to barracuda and remember to “export / import” the database after mysql restart and remeber BACKUP before the changes, its will speed you perfome op

“loose” should be read as “lose.”

What is a loose transaction versus a tight one? You wrote “can loose transactions for last second or two.” What does that mean. I’ve worked in this industry for over 30 years, and I’ve never heard that term before.

With the brand spanking new innodb plugin, will all these apply or will we need to consider changing variables a bit?
