1.6.1. What's New in MySQL 5.1
The following features are implemented in MySQL 5.1. We will add
more detailed information to this section as 5.1 development
continues.
Partitioning: This
capability enables distributing portions of individual
tables across a filesystem, according to rules which can be
set when the table is created. In effect, different portions
of a table are stored as separate tables in different
locations, but from the user point of view, the partitioned
table is still a single table. See
Chapter 17, Partitioning, for further information on
this functionality. (Author: Mikael Ronström)
Plugin API: MySQL 5.1 adds
support for a very flexible plugin API that enables loading
and unloading of various components at runtime, without
restarting the server. Although the work on this is not
finished yet, plugin full-text parsers
are a first step in this direction. This allows users to
implement their own input filter on the indexed text,
enabling full-text search capability on arbitrary data such
as PDF files or other document formats. A pre-parser
full-text plugin performs the actual parsing and extraction
of the text and hands it over to the built-in MySQL
full-text search. (Author: Sergey Vojtovich)

The Instance Manager (IM)
now has some additional functionality:
SHOW instance_name
LOG FILES provides a listing of all log files
used by the instance. (Author: Petr Chardin)
SHOW instance_name
LOG {ERROR | SLOW | GENERAL}
size retrieves a
part of the specified log file. (Author: Petr Chardin)
SET
instance_name.option_name=option_value
sets an option to the specified value and writes it to
the config file See Section 5.4, “mysqlmanager — The MySQL Instance Manager”,
for more details on these new commands. (Author: Petr
Chardin)
