Hello
I have a table partitioned like this
drop table if exists s cascade;
create table s
(
version int not null,
a int,
b int
) partition by list (version);
-- Add tens of partitions
-- Load millions of rows in each partition
-- Then I want to be able to do this wothout scanning all partitions for the
highest version number.
select s.* from s where s.version = (select max(version) from s);
I could add an index on the version column. But the only use would be to the
newest partition, so that seems a bit like overkill, indexing 100 of milliomns
of rows.
Is there another way to do this in a cheaper way.
For now I have created a materialized view based on the select above, thus only
scanning for max partition only once.
