I have a somewhat large table (abt 4 million records) and when I do an ALTER
TABLE to add a column the database hangs. I have plenty of free disk space
and memory. The server version is 4.0.17 and the table type is InnoDB. Has
anyone experienced this behavior?
Thanks!

I don't recall exactly what options I selected in September when I
installed the beta v5.0.4 on my development machine, But, as I started
to develop and then backup data, I noticed that my tables are all using
the storage engine: InnoDB.
Can someone jog my memory and tell me what options cause that to be the
default ?
I'm on the fence, b/w...

the 4.0.12 version, almost immediately ran into a locking issue with
INSERTs, DELETEs, and transactions.
Given the following table:
