I have a huge table (OK, OK ... most of you have seen bigger ;-) and would like to partition it (I think it
would help performance).
One of the fields in the table is a "weeknumber" (not number within a year, but number of weeks since some date) and I think since all queries contain
WHERE AGBWEEK >= whatever AND AGBWEEK <=something ...
this would be the best field to partition the table on. Right?
I thought I could create a partition for every N weeks.
But we get new data every week so the upper bound - the maximum week number - changes.
So ... what should I do?
Should I "prealocate" several partitions for upcoming weeks?
And then repartition the table after the last partition gets too big?
Or is is possible to split the last partition when necessary ? Or instruct Oracle to create a new partition every time the partitioning field increases above a limit?
Thanks and please forgive my misunderstandings. (I'm sure there are many.)
