Listed below are the required features to manage >1TB VLDBs:

- Global index on the primary table (across partitions)
- Local indexes on each partitions.
- Select fld1,... from <PrimaryTable>.<PartitionName> WHERE ....
- sqldump : dump entire table or selected partitions
- import entire table or selected partitions.
- Move partition from one tablespace to another/new.
- Merge,split , rename,truncate and drop partitions. Also set status to active or inactive.
- Option to load any partition to cache (heap storage engine may not help)
- Able to create view on a set of selected partitions.
- Optimization hints for Index usage and other select / join operations.
- Don't allow to drop all the partitions. Atleast the table must have one active partition.
- Row counts are cached for each partitions and for the entire table so that
the select count(*) from <table>.<partition> will display the count faster.
