Aviem Zur updated BEAM-1465:
----------------------------
Description:
{{FileBasedWriter}} API does not have a natural place to flush/close resources
opened by the writer.
For example, if you create an {{OutputStream}} in your {{Writer}} using the
{{FileBasedSink}}'s channel and this {{OutputStream}} buffers outputs, there is
no natural place to call its {{flush()}} method.
Maybe something like {{finishWrite()}} to match the existing
{{prepareWrite(WritableByteChannel channel)}} can work.
