BELUGA BEHR commented on AVRO-2056:
-----------------------------------
[~gszadovszky] I'm sorry, but I do not understand your request to "add the Perf
change." I did not change the Perf test to accomplish the testing other than
un-comment the direct binary encoder:
{code}
Encoder e = encoder_factory.binaryEncoder(out, null);
// Encoder e = encoder_factory.directBinaryEncoder(out, null);
{code}
> DirectBinaryEncoder Creates Buffer For Each Call To writeDouble
> ---------------------------------------------------------------

> Key: AVRO-2056
> URL: https://issues.apache.org/jira/browse/AVRO-2056
> Project: Avro
> Issue Type: Improvement
> Components: java
> Affects Versions: 1.7.7, 1.8.2
> Reporter: BELUGA BEHR
> Assignee: BELUGA BEHR
> Priority: Minor
> Attachments: AVRO-2056.1.patch

>
> Each call to {{writeDouble}} creates a new buffer and promptly throws it away
> even though the class has a re-usable buffer and is used in other methods
> such as {{writeFloat}}. Remove this extra buffer.
> {code:title=org.apache.avro.io.DirectBinaryEncoder}
> // the buffer is used for writing floats, doubles, and large longs.
> private final byte[] buf = new byte[12];
> @Override
> public void writeFloat(float f) throws IOException {
> int len = BinaryData.encodeFloat(f, buf, 0);
> out.write(buf, 0, len);
> }
> @Override
> public void writeDouble(double d) throws IOException {
> byte[] buf = new byte[8];
> int len = BinaryData.encodeDouble(d, buf, 0);
> out.write(buf, 0, len);
> }
> {code}
