表压缩有三个选项
1、page
2、row
3、none
-----------------------------------------------------------------------------------------------------------------------
三种设置方式:
第一种:定义时指定
create table table_name(....)
with
(data_compression = none | page | row);
第二种:修改时指定
alter table table_name
rebuild
with
(datacompression = page | row | none);
第三种:针对特定分区
create table table_name(...)
on partition_schem_test(column_name)
with
(data_compression = page on partition(1 to 3),
data_compression = row on partition(4));
---------------------------------------------------
alter table table_name
rebuild partition = 4
with
(data_compression = page);
