the update event can't resolve fields name?

UpdateRowsEventData{tableId=119, includedColumnsBeforeUpdate={0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, includedColumns={0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, rows=[ {before=[xxx], after=[xxx]} ]}

not a bug in binlog-connector-java, a mysql limitation. maxwell and debezium both have to go to ungodly lengths to get fields names.

Note...
Older MySQL/MariaDB binlog doesn't contain information about field names.
MySQL 8.0+ and MariaDB 10.5+ have extended metadata which contain data like:

• column names
• column charset
• signedness of number columns
• enum/set values (those are transmitted as numbes in binary log)
• primary key
• ...

Library parses data data to TableMapEventMetaData structure.
