Memcached Functions for MySQL 0.8 (Default branch)
This is a set of MySQL UDFs (user defined functions) to work with memcached using libmemcached. With these functions, you can get, set, append, prepend, delete, increment, and decrement objects in memcached, provide statistics, and set which servers to use and which behavior the server connections will use. These functions can be combined with MySQL triggers. You can also use memcached as a global sequence generator for MySQL by making use of the increment function. These functions are compatible with all versions of MySQL.License: GNU General Public License (GPL)Changes:
memc_servers_behavior_get(''), memc_list_distribution_types(), memc_list_hash_types(), memc_behavior_get() (an alias to memc_servers_behavior_get() ), and memc_behavior_set() (an alias to memc_servers_behavior_set() ) functions were added. memc_servers_behavior_set() now works for all types of behaviors - Boolean, named behaviors (string), and numeric.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.
