Review comment:
Any bug in this space is an error in the implementation of the IO
connector so these error messages will mostly come up during development and
then if any bugs are discovered during the usage the user won't be able to do
much and this will go to the Beam community/IO author to fix.
If you really want to, adding a `format` method and creating a subclass
would make more sense then having effectively a copy.

> HL7v2IO.ListHL7v2Messages should be refactored to support more parallelization
> ------------------------------------------------------------------------------

> Key: BEAM-9856
> URL: https://issues.apache.org/jira/browse/BEAM-9856
> Project: Beam
> Issue Type: Improvement
> Components: io-java-gcp
> Reporter: Jacob Ferriero
> Assignee: Jacob Ferriero
> Priority: Minor
> Time Spent: 3h 10m
> Remaining Estimate: 0h
>
> Currently the List Messages API paginates through in a single ProcessElement
> Call.
> However we could get a restriction based on createTime using Messages.List
> filter and orderby.
>
> This is inline with the future roadmap of HL7v2 bulk export API becomes
> available that should allow splitting on (e.g. create time dimension).
> Leveraging this bulk export might be a future optimization to explore.
>
> This could take one of two forms:
> 1. dyanmically splitable via splitable DoFn (sexy, beam idiomatic: make
> optimization the runner's problem, potentially unnecessarily complex for this
> use case )
> 2. static splitting on some time partition e.g. finding the earliest
> createTime and emitting a PCollection of 1 hour partitions and paginating
> through each hour of data w/ in the time frame that the store spans, in a
> separate ProcessElement. (easy to implement but will likely have hot keys /
> stragglers based on "busy hours")
