I want to set up a large table on postgresql 12.4, using declarative partitioning to partition by record creation date. I'd like to have recent records in small partitions but old records in a few larger partitions, so I want merges. The merges should be concurrent, in the sense that they lock out readers or writers only for very short intervals if at all.
Once a date has passed is the table for that date effectively read-only?
No, old records get updated from time to time, although updates are much less common than for recent records.
