- Create a table with partition and lifecycle:
|
|
|
|
`create table {{table_name}} ({{col}} {{type}}) partitioned by ({{col}} {{type}}) lifecycle {{days}};`
|
|
|
|
- Create a table based on the definition of another table:
|
|
|
|
`create table {{table_name}} like {{another_table}};`
|
|
|
|
- Add partition to a table:
|
|
|
|
`alter table {{table_name}} add parition ({{partition_spec}});`
|
|
|
|

|
|
|
|
`alter table {{table_name}} drop partition ({{partition_spec}});`
|
