Hi,
If i have inconsistent data on nodes
Scenario :
I have 2 DCs each with 3 nodes
and I have inconsistent data on them

node 1,2,3,4,5 have
P1,100,A,val1,w1
P1,100,B,val2,w2

node 6 has
P1,100,A,val1,w1
P1,100,B,val2,w2
P1,200,C,val3,w3
P1,200,D,val4,w4

col1, col2, col3,col4,col5 in table
Primary key (col1, col2, col3)

Now i execute the query from CQLSH
update mykeyspace.my_table_1 set col5 = 'w_x' where col1='P1' and col2=200
and col3='C' IF EXISTS;

Is it possible that
node 1,2,3,4,5 will get the entry
P1,200,C,null,w_x

I.e. IF EXISTS is checked per node or only once and then execute on all?

Thanks
Siddharth Verma
