MySQL Database Analytics with InfiniDB from Calpont – Part 2
In Part 1 of this article, I took you through some of the reasons why a column-oriented database based on MySQL can be compelling. We also examined the architecture of InfiniDB, which is an open source analytic, reporting, and read-intensive database, and how its modular design helps you scale both up and out. Now let's kick the tires of the database so you can see these things in action.

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).

+--------------------------+-----------------------------------+-------------------------------------+
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.
