Размер таблицы — MariaDB Columnstore против InnoDB

Каждый анализ, который я нашел в ColumnStore от MariaDB, утверждает, что он использует меньше места на диске, чем обычные механизмы, такие как InnoDB, например: https://www.percona.com/blog/2017/03/17/column-store-базаданных-benchmarks-mariadb-columnstore-vs-clickhouse-vs-apache-spark/

Но это было не то, что я нашел в своих тестах

CREATE TABLE `innodb_test` (id int, value1 bigint, value2 bigint, value3 bigint, value4 bigint, value5 bigint) ENGINE=innodb;

CREATE TABLE `columnstore_test` (id int COMMENT 'compression=2', value1 bigint COMMENT 'compression=2', value2 bigint COMMENT 'compression=2', value3 bigint COMMENT 'compression=2', value4 bigint COMMENT 'compression=2',value5 bigint COMMENT 'compression=2') ENGINE=columnstore;

Вставьте в таблицы 1 миллион строк (5 столбцов) со значением 0:

INSERT INTO innodb_test
SELECT CONCAT(a1.id,a2.id,a3.id,a4.id,a5.id,a6.id),
0,0,0,0,0
from 
  (select 0 as id union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) a1, 
  (select 0 as id union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) a2,
  (select 0 as id union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) a3,
  (select 0 as id union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) a4,
  (select 0 as id union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) a5,
  (select 0 as id union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) a6;

INSERT INTO columnstore_test SELECT * FROM innodb_test;

Размер таблицы columnstore больше, чем таблица innoDB:

call columnstore_info.table_usage(NULL, 'columnstore_test');
+--------------+------------------+-----------------+-----------------+-------------+
| TABLE_SCHEMA | TABLE_NAME       | DATA_DISK_USAGE | DICT_DISK_USAGE | TOTAL_USAGE |
+--------------+------------------+-----------------+-----------------+-------------+
| size_comp    | columnstore_test | 352.05 MB       | 0 Bytes         | 0 Bytes     |
+--------------+------------------+-----------------+-----------------+-------------+

SELECT table_name, (data_length + index_length) / (1024 * 1024) "Size in MB"  FROM information_schema.tables WHERE table_schema = schema() AND table_name = 'innodb_test';
+-------------+------------+
| table_name  | Size in MB |
+-------------+------------+
| innodb_test | 71.6094    |
+-------------+------------+

Кроме того, если я создаю таблицу без сжатия, размер будет таким же:

CREATE TABLE `columnstore_no_compression` (id int COMMENT 'compression=0', value1 bigint COMMENT 'compression=0', value2 bigint COMMENT 'compression=0', value3 bigint COMMENT 'compression=0', value4 bigint COMMENT 'compression=0',value5 bigint COMMENT 'compression=0') ENGINE=columnstore;

INSERT INTO columnstore_no_compression SELECT * FROM innodb_test;

call columnstore_info.table_usage(NULL, 'columnstore_no_compression');
+--------------+----------------------------+-----------------+-----------------+-------------+
| TABLE_SCHEMA | TABLE_NAME                 | DATA_DISK_USAGE | DICT_DISK_USAGE | TOTAL_USAGE |
+--------------+----------------------------+-----------------+-----------------+-------------+
| size_comp    | columnstore_no_compression | 352.00 MB       | 0 Bytes         | 0 Bytes     |
+--------------+----------------------------+-----------------+-----------------+-------------+

Это ожидаемое поведение или я делаю что-то не так?
