[if-jeremy]

Describe the bug A clear and concise description of what the bug is.

Metadata file does not include binlog position when dumping RDS Aurora 2 (mysql 5.7) database

To Reproduce Command executed:

• mydumper with all the parameters

mydumper --ssl \
-h {hostname} -o /dump --verbose=3 --port=3306 \
--kill-long-queries --chunk-filesize=5120 --build-empty-files \
--events --routines --triggers --compress --less-locking \
--success-on-1146 -B db1,db2,db3 \
-u {user} -p \"{password}\""

What mydumper and myloader version has been used?

mydumper v0.16.3-2, built against MySQL 8.4.0 with SSL support

Expected behavior A clear and concise description of what you expected to happen.

Expect to see master log position in the metadata file

Environment (please complete the following information):

• OS version: [e.g. CentOS 7.9, Ubuntu 20.04]
• MyDumper version: [ mydumper --version ]

Amazon Linux 2023 for ARM64, mydumper 0.16.3-2 (within Docker container)

Additional context Add any other context about the problem here.

I suspect this is because of the patch https://github.com/mydumper/mydumper/pull/1512 - SHOW MASTER STATUS is deprecated in 8.2 - but it still needs to be used for older versions that do not support show_binary_log_status
