Memcached Functions for MySQL 0.5 (Default branch)
Memcached Functions for MySQL is a set of MySQL UDFs (user defined functions) to work with memcached using libmemcached. With these functions you get, set, append, prepend, and delete objects in memcached. You can also use memcached as a global sequence generator. With these functions you can use triggers to control your object caches. License: GNU General Public License (GPL) Changes:
This release adds expiration argument functionality to all functions that utilize it in libmemcached (set, add, and replace). Behavior has been updated to correspond with the latest libmemcached. An args processing function has been added to reduce redundancy. Tests have been added for expiration testing.Image

ndb_delete_all

NDB_DELETE_ALL(1)					       MySQL Database System						 NDB_DELETE_ALL(1)

NAME

       ndb_delete_all - delete all rows from an NDB table

SYNOPSIS

       ndb_delete_all options

DESCRIPTION

       ndb_delete_all deletes all rows from the given NDB table. In some cases, this can be much faster than DELETE or even TRUNCATE TABLE.
	       Usage

	   ndb_delete_all -c connect_string tbl_name -d db_name

       This deletes all rows from the table named tbl_name in the database named db_name. It is exactly equivalent to executing TRUNCATE
       db_name.tbl_name in MySQL.

       The following table includes options that are specific to ndb_delete_all. Additional descriptions follow the table. For options common to
       most MySQL Cluster programs (including ndb_delete_all), see Options Common to MySQL Cluster Programs(1).

       Table 17.16. ndb_delete_all Options and Variables: MySQL Cluster NDB 7.2

       +--------------------------+-----------------------------------+-------------------------------------+

       o   --transactional, -t

	   Use of this option causes the delete operation to be performed as a single transaction.

	       Warning
	       With very large tables, using this option may cause the number of operations available to the cluster to be exceeded.
