That sounds interesting. You might turn on verbose logging for SQL
operations (openjpa.jdbc.SQL) and see what queries are actually being
executed. The logging section of the OpenJPA manual explains this.

Hello,
I'm not at all an expert in databases, so I don't know if this is a JPA
thing or a DB thing.
In any case, I'm using Postgresql. Using the findAll( Class,
Collection ) method, I am doing a lookup by PK. Since there is an index
like so on the table:
"table_pkey" PRIMARY KEY, btree (id)
I would have expected the lookup to be very fast.
With a collection of about 100 ids, the lookup takes almost 30 seconds,
which does not seem right to me.
Any ideas where I should begin to look?
Thanks!
