Summary: There are two buffer copies in ChunkOutputStream Key: HDDS-372 URL: https://issues.apache.org/jira/browse/HDDS-372 Project: Hadoop Distributed Data Store Issue Type: Improvement Components: Ozone Client Reporter: Tsz Wo Nicholas Sze Assignee: Tsz Wo Nicholas Sze Currently, there are two buffer copies in ChunkOutputStream # from byte[] to ByteBuffer, and # from ByteBuffer to ByteString. We should eliminate the ByteBuffer in the middle. For zero copy io, we should support WritableByteChannel instead of OutputStream. It won't be done in this JIRA. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
