这个元数据表是percona server里加入的 https://docs.percona.com/percona-server/8.0/flexibility/compres ...

--force是默认参数等于已经加上了。
--ignore没有这个参数

INFORMATION_SCHEMA Tables¶

This feature implements two new INFORMATION_SCHEMA tables.
INFORMATION_SCHEMA.COMPRESSION_DICTIONARY¶
Column Name         Description
‘BIGINT(21)_UNSIGNED dict_version’         ‘dictionary version’
‘VARCHAR(64) dict_name’         ‘dictionary name’
‘BLOB dict_data’         ‘compression dictionary string’

This table provides a view of the internal compression dictionary. The SUPER privilege is required to query it.

官方文档里面说这个表是在INFORMATION_SCHEMA 库里面的，并没提及mysql库也存在这张表
