For mow table, delete bitmap of stale rowsets has not been persisted. When be restart, duplicate keys will occur if read stale rowsets.
Therefore, for the mow table, we do not allow reading the stale rowsets. Although this may result in VERSION_ALREADY_MERGED error when query after be restart, its probability of occurrence is relatively low.
Check whether there are complex types in parquet/orc reader in broker/stream load. Broker/stream load will cast any type as string type, and complex types will be casted wrong. This is a temporary method, and will be replaced by tvf.
join commute rule will swap the left and right child. This cause the change of logical properties. So we need recompute the logical properties in plan post process to get the correct result
Default, if less than or equal 32 core, the following are 128, 128, 10240, 10240 in turn.
if greater than 32 core, the following are core num * 4, core num * 4, core num * 320, core num * 320 in turn

Problem:
When create view with projection group_concat(xxx, xxx order by orderkey). It will failed during second parse of inline view
For example:
it works when doing
"SELECT id, group_concat(`name`, "," ORDER BY id) AS test_group_column FROM test GROUP BY id"
but when create view it does not work
"create view test_view as SELECT id, group_concat(`name`, "," ORDER BY id) AS test_group_column FROM test GROUP BY id"
Reason:
when creating view, we will doing parse again of view.toSql() to check whether it has some syntax error. And when doing toSql() to group_concat with order by, it add seperate ', ' between second parameter and order by. So when parsing again, it
would failed because it is different semantic with original statement.
group_concat(`name`, "," ORDER BY id) ==> group_concat(`name`, "," , ORDER BY id)
Solved:
Change toSql of group_concat and add order by statement analyze() of group_concat in Planner cause it would work if we get order by from view statement and do not analyze and binding slot reference to it
When the user imports data, there are some special characters in the data, which will cause the import to fail
