Trawling the binlog with FlexCDC and new FlexCDC plugins for MySQL

Location for InnoDB tablespace in MySQL 5.6.6

There is one new feature in MySQL 5.6 that didn’t get the attention it deserved (at least from me ) : “DATA DIRECTORY” for InnoDB tables. This is implemented since MySQL 5.6.6 and can be used only at the creation of the table. It’s not possible to change the DATA DIRECTORY with an ALTER for […]
