damccorm opened a new issue, #21341: URL: https://github.com/apache/beam/issues/21341
This Issue is to solve similar problems to wha I had in [BEAM-12883.](https://issues.apache.org/jira/browse/BEAM-12883?page=com.atlassian.jira.plugin.system.issuetabpanels%3Aall-tabpanel) Currently there are 2 Coders for Metadata: default one: org.apache.beam.sdk.io.fs.MetadataCoder and enhanced one org.apache.beam.sdk.io.fs.MetadataCoderV2, the last can also decode-encode lastModifiedMillis and it is done in a new coder in order to support backward compatibility. This will be hard to maintain, we will need to create a new coder for any new field that will be added to Metadata. So, as suggested in this [comment: #15510](https://github.com/apache/beam/pull/15510#issuecomment-928390587), we need to have some new generic coder : MetadataDynamicCoder. MetadataDynamicCoder can decode/encode any new fields added to Metadata by sending getter, setter and coder. Imported from Jira [BEAM-13640](https://issues.apache.org/jira/browse/BEAM-13640).
