1. fix datetime ms transfer to s bug
2. fix alter storage policy notify be missing field(datetime, ttl)
3. support alter storage policy use "h, hour, d, day" as ttl filed
Support such grammer:
select * from t_p temporary partition(tp1);
select * from t_p temporary partitions(tp1);
select * from t_p temporary partition tp1;
When light schema change is enabled by default, a column in OLAP scan is retrieved by column unique id instead of the column name. Columns with the same name would use different unique IDs among materialized indexes.
This PR ensures that the column in the OLAP scan node could use the correct column unique id.
This PR defines order_key and having_key binding priority.
1. order key priority
```
select
col1 * -1 as col1 # inner_col1 * -1 as alias_col1
from
t
order by col1; # order by order_col1
```
to bind `order_col1`, `alias_col1` has higher priority than `inner_col1`
2. having key priority
```
select (a-1) as a # inner_a - 1 as alias_a
from bind_priority_tbl
group by a
having a=1;
```
to bind having key, `inner_a` has higher priority than `alias_a`
3. group by key binding priority
```
SELECT date_format(b.k10,
'%Y%m%d') AS k10
FROM test a
LEFT JOIN
(SELECT k10
FROM baseall) b
ON a.k10 = b.k10
GROUP BY k10;
```
group_by_key (k10) binding priority:
- agg.child.output
- agg.output
if binding with agg.child.output failed(the slot not found, or more than one candidate slot found in agg.child.output), nereids try to bind group_by_key with agg.output.
In above example, nereids found 2 candidate slots (a.k10, b.k10) in agg.child.output for group_by_key (k10), binding with agg.child.output failed. Then nereids try to bind group_by_key with agg.output, that is `date_format(b.k10, '%Y%m%d') AS k10`. and finally, group_by_key is bound with `alias k10`
When calculating the statsCalculator of except and intersect, the slotId of the corresponding column was not replaced with the slotId of output, resulting in NPE.
Poll metastore for create/alter/drop operations on database, table, partition events at a given frequency.
By observing such events, we can take appropriate action on the (refresh/invalidate/add/remove)
so that represents the latest information available in metastore.
We keep track of the last synced event id in each polling
iteration so the next batch can be requested appropriately.
when nereids translates PhysicalHashAggreg node to original plan, if the input fragment root is exchange node, nereids assumes that this exchanged node is generated from PhyscialDistirbute node.
But this assumption is not true. For example, sort node could be translated to exchange(merge phase)+sort(local phase).
