# MySQL Cluster analysis for

This is an automated analysis of the database for migration into MySQL Cluster. No warranty is made to the accuracy of the information.

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.

5.1-dd is for tables stored on disk. The ndb_size.pl estimates are experimental and should not be trusted. Notably we don't take into account indexed columns being in DataMemory versus non-indexed on disk.

## Parameter Settings

NOTE the configuration parameters below do not take into account system tables and other requirements.

### Indexes

We assume that indexes are ORDERED (not created USING HASH). If order is not required, 10 bytes of data memory can be saved per row if the index is created USING HASH
