Hello,
We have UUIDs in our tables which are primary keys. But in some cases
we also identify a composite unique key apart from the primary key.
My assumption is that there should be a unique key index created by us using the composite key. And when we fetch using this composite key instead of the primary key we have a performance boost due to the index.
Is this right ? Are there more details I should read to understand this better ? Please point. If I should use the query planner to look at the statistics I will.
.
Thanks,
Mohan
