MySQL Reference Manual for version 4.0.18.
1.6.3 New Features Planned for 5.1
- New functionality
-
FOREIGN KEY
support for all table types, not just InnoDB
.
-
Column-level constraints.
-
Fail-safe replication.
-
Online backup with very low performance penalty. The online backup will
make it easy to add a new replication slave without taking down the
master.
- Speed enhancements
-
New text based table definition file format (`.frm' files) and a
table cache for table definitions. This will enable us to do faster
queries of table structures and do more efficient foreign key support.
-
Optimize the
BIT
type to take 1 bit. (BIT
now takes 1 byte;
it is treated as a synonym for TINYINT
.)
- Usability enhancements
-
Add options to the client/server protocol to get progress notes
for long running commands.
-
Implement
RENAME DATABASE
. To make this safe for all storage engines,
it should work as follows:
-
Create the new database.
-
For every table do a rename of the table to another database, as
we do with the
RENAME
command.
-
Drop the old database.
-
New internal file interface change. This will make all file handling much
more general and make it easier to add extensions like RAID.
