When consuming Alibaba Cloud PolarDB, there is one more column than the fields in the table.

CREATE TABLE test1 (
id bigint(20) NOT NULL COMMENT '主键ID',
bill_type tinyint(2) NOT NULL DEFAULT '1' COMMENT '',
collect_no varchar(32) NOT NULL DEFAULT '' COMMENT '',
create_time timestamp NULL DEFAULT NULL COMMENT '',
PRIMARY KEY (id) USING BTREE,
KEY f_idx_bgt ((cast(create_time as date)))
) ENGINE=InnoDB

KEY f_idx_bgt ((cast(create_time as date)))
After testing, this index is recognized as a column

I used 1.7 and 1.8

com.zendesk mysql-binlog-connector-java 0.29.1

I use this to subscribe to binlog and the columns that appear are normal.

UpdateRowsEventData: UpdateRowsEventData{tableId=11071, includedColumnsBeforeUpdate={0, 1, 2, 3}, includedColumns={0, 1, 2, 3}, rows=[

{before=[21, 2, 2211, null], after=[21, 2, 22111, null]}
]}
