Guys,
I got a Java program to tune. It connects to a 7.4.1 postgresql server
running Linux using JDBC.
The program needs to update a counter on a somewhat large number of
rows, about 1200 on a ~130k rows table. The query is something like
the following:
UPDATE table SET table.par = table.par + 1
WHERE table.key IN ('value1', 'value2', ... , 'value1200' )
This query runs on a transaction (by issuing a call to
setAutoCommit(false)) and a commit() right after the query
is sent to the backend.
The process of committing and updating the values is painfully slow
(no surprises here). Any ideas?
Thanks.
