Except the number of tasks, can we confirm whether to use index from the log
file?
Such as something like keyword for us to search in the log file directly.

Hi All
As you know, some default value of parameters need to adjust for most of
cases, this discussion is for collecting which parameters' default value
need to be optimized:
1. TABLE_BLOCKSIZE:
current default is 1G, propose to adjust to 512M
2.
Please append at here if you propose to adjust
If the index be used, the number of tasks would be less.
Can you share your script (create table script and query script), let us
check if you created the effective index for filter columns.
Regards
Liang

Hi Rahul
I suggest only doing "Query HINT".
Please finalize the query script :
select * from t1 [in SEGMENTS(1,3,5)] or SELECT /*+SEGMENTS(1,3,5) */ from
t1
