I have written a program in C to parse large XML files and then create files with insert statements. Some other process would ingest the files into a MySQL database. This data will serve as a indexing service so that users can find documents easily. I have chosen InnoDB for the ability of row-level locking. The C program will be gene...
In MySQL, using statement based replication I assume that every SQL statement gets executed on the slave exactly the same way as on the master. However, when I run the statement: LOAD DATA INFILE 'filename' INTO SomeTable; I'm not sure if the file needs to exist on the slave the same way at it does on the master. Can someone point me ...
