> Key: BEAM-12883
> URL: https://issues.apache.org/jira/browse/BEAM-12883
> Project: Beam
> Issue Type: Improvement
> Components: sdk-java-core
> Reporter: Brachi Packter
> Priority: P3
>
> Currently, there is a separated coder for Metadata which cares about `Metadata#lastModifiedMillis()`.
> The issue is that the `ReadableFileCoder` always uses the default `Metadata` coder.
> We need to create a similar coder for `ReadableFileCoder`: ``ReadableFileCoderV2` which just use the corresponding `MetadataCoderV2`.
> Without doing so `lastModifiedMillis` will remain zero.
> There is also no way to create custom coder in our side since `FileIO.ReadableFile` has no public method to initiate new instance of it.
