Is Query with Union All on federation run parallel?

1 New Member
Hi All,

I have federation setup on db2 database (X) for 4 different db2 servers (e.g. A1, A2, A3, A4).
I created below nicknames on X database which uses 4 db2 servers.
A1_EMP_DIM
A2_EMP_DIM
A3_EMP_DIM
A4_EMP_DIM

Is below query run parallel on 4 server (A1, A2, A3, A4)?

Select EMP_ID,EMP_NAME from X.A1_EMP_DIM
Union All
Select EMP_ID,EMP_NAME from X.A2_EMP_DIM
Union All
Select EMP_ID,EMP_NAME from X.A3_EMP_DIM
Union All
Select EMP_ID,EMP_NAME from X.A4_EMP_DIM

Regards
