> The
> [FLUSH_PASSED_TO_STREAM|https://github.com/codehaus/jackson/blob/1.8/src/java/org/codehaus/jackson/JsonGenerator.java#L120]
> feature of jackson's 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.
