Hello all,
I run a query file through impala-shell -f command, and that file
contains 10 queries, why the first query cost much of time ?
Yes, it's exactly the first query in that file, I have tried to exchange
the first one and the second one, the first query in that file(Q2 after
exchange the position) cost much time. like the following pic,
Anyone can explain the impala-shell execution mechanism to me ?
Thanks so much.
