Hello.
According to:
http://dev.mysql.com/doc/refman/5.0/en/innodb-locks-set.html
INSERT ... SELECT set a non-next-key lock on each row. So in most cases
you should be able to insert the record into Y. Please, provide
the CREATE statement for table Y and the output of 'show variables'
statement. In my opinion, the problem could be in keys, if they're
present in the table. Include the output of SHOW PROCESSLIST and
SHOW INNODB STATUS as well.

I use MySQL 5.0.15
I have about 5 billion rows in table X, i create another table Y with
the same stucture with X
CREATE TABLE Y LIKE X;
Both X and Y is the InnoDB table, since i believe that both work on the
"row locking" models
I try to initiate 2 session
First session try to INSERT all of data from X to Y like this
INSERT INTO Y SELECT * FROM X;
After a while (i need a long time to finish this Query), i start my
second session and try
to insert a data into Y
What happened later make me confuse, because
INSERT INTO Y VALUES (something) is just hang on, seems waiting another
operation to be finished
Why concurrent insert is not working?
FYI, i use standar configuration from MySQL
Any explanation?
Thx
