I have table where I store sample values (1 record per value). Table get's huge (tens of millions of records).
I don't need to filter based on value, just quite frequently add new value and from time to time cleanup old values.
I was wondering about storing samples in one dimensional array instead (so 1 record per "sample type").
Does PG handles well such huge arrays?
Is adding new element with array_append will rewrite entire array or just add one element (IO concern)?
Any thoughts?
Thanks!
