David Mollitor moved HIVE-24226 to PARQUET-1918:
------------------------------------------------

Workflow: patch-available, re-open possible (was: no-reopen-closed,

Project: Parquet (was: Hive)
> Avoid Copy of Bytes in Protobuf BinaryWriter
> --------------------------------------------
>
> Key: PARQUET-1918
> URL: https://issues.apache.org/jira/browse/PARQUET-1918
> Project: Parquet
> Issue Type: Improvement
> Reporter: David Mollitor
> Assignee: David Mollitor
> Priority: Minor
>
> {code:java|title=ProtoWriteSupport.java}
> class BinaryWriter extends FieldWriter {
> @Override
> final void writeRawValue(Object value) {
> ByteString byteString = (ByteString) value;
> Binary binary = Binary.fromConstantByteArray(byteString.toByteArray());
> recordConsumer.addBinary(binary);
> }
> }
> {code}
> {{toByteArray()}} creates a copy of the buffer. There is already support
> with Parquet and Protobuf to pass instead a ByteBuffer which avoids the copy.
