# BUGS
# ----
# - enum/set is 0 byte storage! Woah - efficient!
# - DECIMAL is 0 byte storage. A bit too efficient.
# - some float stores come out weird (when there's a comma e.g. 'float(4,1)')
# - no disk data values
# - computes the storage requirements of views (and probably MERGE)
# - ignores character sets.
# - ignores character sets?

<h1>MySQL Cluster analysis for <TMPL_VAR NAME="db" escape="html"></h1>
<p>This is an automated analysis of the <TMPL_VAR NAME="DSN" escape="html"> database for migration into <a href="http://www.mysql.com/">MySQL</a> Cluster. No warranty is made to the accuracy of the information.</p>
<p>This information should be valid for MySQL 4.1 and 5.0. Since 5.1 is not a final release yet, the numbers should be used as a guide only.</p>
<p>5.1-dd is for tables stored on disk. The ndb_size.pl estimates are <b>experimental</b> and should not be trusted. Notably we don't take into account indexed columns being in DataMemory versus non-indexed on disk.</p>
<h2>Parameter Settings</h2>
<p><b>NOTE</b> the configuration parameters below do not take into account system tables and other requirements.</p>
