I know that, but partitioning by county makes the DB a lot easier to
maintain.
I have to work that way because I'm dealing with criminal records, and
they are separated by county with a ton of different files, so for
many of them I have to clear the table and reload the whole county
every time I get an update. Easier on partitions... :-)
Table size can be anywhere from 8000 to 3 million records, depending
on the county.
The best way to do that would be having a table partitioned over 3077
filegroups, so storing the data will go by COUNTY in this way:
CA_ALAMEDA
CA_ALPINE
CA_AMADOR
CA_BUTTE
CA_CALAVERAS
CA_COLUSA
CA_CONTRA_COSTA
CA_DEL_NORTE
CA_EL_DORADO
CA_FRESNO
CA_GLENN
CA_HUMBOLDT
CA_IMPERIAL
CA_INYO
With the COUNTY as the partition Parameter.
But, before trying, can I have 3077 files in ONE partition, and drop
all the states stuff?
Thanks!
Piero
