[GitHub] [incubator-doris] xy720 opened a new issue #3389: [New Feature] Batch update partition's property in one command
xy720 opened a new issue #3389:
URL: https://github.com/apache/incubator-doris/issues/3389
As [ISSUE #2299] saying, if users wanna update the replication number of a table, users can only alter partition one by one.
We should support updating partitions' properties of a table in one command.
1、For unpartitioned table, we should support update table's property directly.(pr #3360 )
```
alter table test_tbl set ("replication_num" = "3");
```
2、For range table, we should let user know they are updating multi-partitions and let them to specify partitions that needed update.
Example:
- replication_num
```
alter table tbl_name modify partition (p1, p2, p3) set ("replication_num" = "3");
```
- storage_medium && storage_cooldown_time
```
alter table tbl_name modify partition (p1, p2, p3) set ("storage_medium" = "SSD", "storage_cooldown_time" = "2018-01-01 12:00:00");
```
- in_memory
```
alter table tbl_name modify partition (*) set ("in_memory" = "true");
```
