Assume this schema
CREATE TABLE t(
a int,
b int,
c int,
d int,
e text,
f date,
g int,
PRIMARY KEY (a,b)
)
I we create following mv
CREATE MATERIALIZED VIEW t_mv as
select a,b,c,d from t where c is not null and d is not null
PRIMARY KEY (c,d,a,b);
What happens if we run this query
UPDATE t SET g=1 WHERE a=10 AND b = 20
As you can see "g" is excluded in "t_mv" , I want to know what cassandra
doing internaly?
Is there any overhead for t_mv , or cassandra smartly detect there is no
changes for t_mv and no-operation
for example If we have 10 materialized view like above-mentioned , is
Update that excluded in mv impact performance? or the performance in equal
to when there is no mv
