PROBLEM: Slow Retrieval !!

Hi,

My company is going to launch new plant automation product having plant history module. Our competitor is using MS SQL Server. They are storing data and index in very small foot print in *.std and *.onx files respectively.

We've chosen MySQL database. MyISAM engine for configuration information and Archive Engine for history information due to its small storage size and fast rate of insertion then MyISAM.

My RnD is badly affecting due to very slow retrieval performance.
Reason being limited to 1024 partitions on windows platform and non avilibility of index (each partition contains +500 Million records).

#########
THE SUCCESS OR FAILURE OF MY RND FOR DB SELECTION DEPENDS UPON RETRIEVAL PERFORMANCE OF HISTORY DATA FROM HUGE STORAGE (1000 GBs) IN ARCHIVE ENGINE TABLE. PLZ LET US KNOW IF WE CAN HAVE INDEX SUPPORT (ID INT, DATETIME) IN ARCHIVE ENGINE?
#########

We are unable to use MyISAM bcz we can't get close to storage + insertion efficiency of competitor.

Thank you,
IR
