Hi Team,
I need some help or suggestions for the below issue. Please provide
answers what to do now. We re in critical position to handle the issue.
Issue: We upgraded postgresql from 10 to 14 version, post to the upgrade
, queries are running very slower than normal expected time. As well as
the queries are not getting completed . We did vacuum analyze, index
recreation and analyze statements etc but no luck still the job queries
are running slower like 10hrs , 14hrs . So please help what we need to
do to fix the issue.-
Actually we have spark scala application that will use JDBC driver to
make connection to the postgresql and then execute the queries. Before
upgrade the same application used to complete in very lesser time like
10mts but now its taking 14hrs and not getting completed.
Not sure why upgrade making slower in performance. Previously the job
used to complete in lesser time.
Please advise and provide suggestion what inorder to do fix the issue.
Kindly help and waiting for good reply with exact solutions
More information needed:
1) OS and version?
2) Where is server hosted, on your machines or a service?
3) The hardware specifications for the machine?
4) How was the upgrade done?
5) An example of a slow query with the output of EXPLAIN <the_query>
6) What version of the JDBC driver?
