We have zero-copy APIs. They can use [HasByteBuffer.getByteBuffer()](https://grpc.github.io/grpc-java/javadoc/io/grpc/HasByteBuffer.html)+InputStream.skip() to loop through the ByteBuffers. If they want to access all the byte buffers simultaneously (as skip() will deallocate the last byte buffer, just like read() does), then they can use InputStream.mark(). If they want to take over ownership of the ByteBuffers, then they can use [Detachable.detach()](https://grpc.github.io/grpc-java/javadoc/io/grpc/Detachable.html).","author":{"url":"https://github.com/lidavidm","@type":"Person","name":"lidavidm"},"datePublished":"2025-12-29T04:31:32.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/939/arrow-java/issues/939"}
