- `CANCEL MATERIALIZED VIEW TASK taskId on mvName`
- CANCEL MATERIALIZED VIEW TASK, tasks("type"="mv") and jobs("type"="mv") support check auth use priv of mv
- tasks and jobs add column mvName and mvDbName,you can use `select * from tasks("type"="mv") where MvName="xxx"` get all tasks of mv
- fix `desc mv all` error
- fix p0 The task sequence is incorrect
Additional deleted filter condition will be materialized column be at the end of the block,
after _output_column_by_sel_idx will be erase, we not need to filter it,
so erase it from _columns_to_filter in the first next_batch.
Eg:
delete from table where a = 10;
select b from table;
a column only effective in segment iterator, the block from query engine only contain the b column,
so no need to filter a column by expr.
The first time load data to a partition, we need to analyze the partition columns even when the health rate is high. Because if not, the min max value of the column may not include the new partition values, which may cause bad plan.
Fix query rewrite by mv fail when self join, after fix query like following can be rewrited
