Hi all,
I've run pgbench with a scale of 2000, and have noticed that the %
done goes a bit wonky:
thom@bison:~$ pgbench -i -s 2000 pgbench
NOTICE: table "pgbench_history" does not exist, skipping
NOTICE: table "pgbench_tellers" does not exist, skipping
NOTICE: table "pgbench_accounts" does not exist, skipping
NOTICE: table "pgbench_branches" does not exist, skipping
creating tables...
100000 of 200000000 tuples (0%) done.
200000 of 200000000 tuples (0%) done.
300000 of 200000000 tuples (0%) done.
...
2000000 of 200000000 tuples (1%) done.
...
20000000 of 200000000 tuples (10%) done.
...
21500000 of 200000000 tuples (-10%) done.
...
23000000 of 200000000 tuples (-9%) done.
...
31000000 of 200000000 tuples (-5%) done.
...
41000000 of 200000000 tuples (0%) done.
and so on, and so forth.
Presumably this is just an int overflowing repeatedly.
