Currently, Doris does not support multi-table materialized view.
So the mv with join is not supported yet.
Doris only support mv for single table, with some certain aggregation such as
sum, min, max, count, count(dinstinct)
For example, there is a base table A with column (k1, k2, v1, v2), you c
Thanks for the reply!
I do understand from doc that the incremental update of MV is triggered
upon base table change.
But I cannot find the actual code in Doris code base that does the update,
specifically the actual incremental plan (tree of operator generated by the
optimizer) to update the vie
It controls by load process.
After a mv is built, all following load task will generate many copies of
import data to base table and all materialized views.
So the incremental update happens on every load task.
