> The FLUSH_PASSED_TO_STREAM feature of JSONGenerator controls if flush calls
> to JsonEncoder are passed to the underlying stream. The default value for
> this is true causing the underlying stream to be flushed every time
> encoder.flush is called. Currently, JsonEncoder doesn't provide a way to
> change this behaviour. In many scenarios, a flush call is made to the encoder
> with the intention of flushing the buffer to the underlying stream, and not
> the stream itself, which has a detrimental impact on performance. The patch
> provided creates a way to specify the default behaviour of underlying
> JSONGenerator during JsonEncoder's initialization itself. This will be
> extremely helpful in scenarios such as Hadoop's MR Evenwriter, allowing the
> caller to set the desired behaviour for optimal performance.
