Hi,
pls tell me, I am currently running 2nd run in my box, (New attempt 2), and its in the "Attempting vacuum" phase.
What is it supposed to do next?
I got no errors , it has gotten my machine to its knees.
The jar has an endless while loop. Thus please kill the PID when you are done testing. It loosely follows the following:
BEGIN;
CREATE TABLE x (id BIGSERIAL PRIMARY KEY, payload1 VARCHAR, payload2 VARCHAR, payload3 VARCHAR, payload4 BIGINT, payload5 BIGINT);
/* Repeat until 2,000,000 rows are inserted */
INSERT INTO x (id, payload1, payload2, payload3, payload4, payload5) VALUES (random values of varying length/size to force random toast usage);
COMMIT;
VACUUM (ANALYZE, FULL);
BEGIN;
/* Repeat until all 2,000,000 rows are updated */
UPDATE x SET payload1 = , payload2 = , payload3 = , payload4 = , payload5 = ... again random values of varying length/size to force random toast usage
COMMIT;
VACCUM (ANALYZE, FULL);
If the error is going to occur it will happen during the second "Attempting vacuum" phase.
1st vacuum:
c.setAutoCommit(true);
System.out.println("Attempting vacuum");
c.prepareCall("VACUUM (FULL, ANALYZE, VERBOSE) x").execute();
System.out.println("Vacuum end. 30 sec sleep");
Thread.sleep(60000);
2nd vacuum:
System.out.println("Attempting vacuum");
c.prepareCall("VACUUM (FULL, ANALYZE, VERBOSE) x").execute();
System.out.println("Vacuum completed");
Thread.sleep(30000);
System.out.println("Dropping the table");
c.createStatement().execute("drop table if exists x");
Thread.sleep(30000);
Hope this helps!
Best wishes,
Harry
