DDL 解析异常（JSON、GENERATED）

我遇到一个问题：

MemoryTableMeta过程中，遭遇了parse faield，表用了JSON类型、GENERATED计算列； 希望能通过解析，或者有其他自动跳过的方式吗？ 我尝试了忽略ddl，但是看起来还是需要先通过表结构解析缓存的。

canal版本：1.1.2 表结构如下：

CREATE TABLE table01 ( id bigint(20) unsigned NOT NULL AUTO_INCREMENT COMMENT 'id', for_type tinyint(4) unsigned NOT NULL DEFAULT '1' COMMENT '', for_id bigint(20) NOT NULL DEFAULT '0' COMMENT '', index_date int(10) NOT NULL DEFAULT '0' COMMENT '', index_minute int(4) unsigned zerofill NOT NULL DEFAULT '0000' COMMENT '', detail json NOT NULL COMMENT '统计信息 ', created_at timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, sum_order int(11) GENERATED ALWAYS AS (json_extract(detail, '$.sum_total')) VIRTUAL, finish_order int(11) GENERATED ALWAYS AS (json_extract(detail, '$.sum_finished')) VIRTUAL, rate_timeliness int(11) GENERATED ALWAYS AS (json_extract(detail, '$.rate_timeliness')) VIRTUAL, unfinish_order int(11) GENERATED ALWAYS AS (json_extract(detail, '$.sum_unfinished')) VIRTUAL, count_is_timeliness int(11) GENERATED ALWAYS AS (json_extract(detail, '$.count_is_timeliness')) VIRTUAL COMMENT '', count_total int(11) GENERATED ALWAYS AS (json_extract(detail, '$.count_total')) VIRTUAL COMMENT '', cancel_order int(11) NOT NULL DEFAULT '0' COMMENT '', sum_wait_grap int(11) GENERATED ALWAYS AS (json_extract(detail, '$.sum_wait_grap')) VIRTUAL, sum_wait_distributing int(11) GENERATED ALWAYS AS (json_extract(detail, '$.sum_wait_distributing')) VIRTUAL, PRIMARY KEY (id), KEY day_minute (index_date, index_minute), KEY type_id (for_type, for_id), KEY for_time_id (for_id, index_date, index_minute) ) ENGINE = InnoDB AUTO_INCREMENT = 1147683045 DEFAULT CHARSET = utf8 COMMENT = '实时指标'
