Gopal V created HADOOP-10047: -------------------------------- Summary: Allow Compressor/Decompressor APIs to expose a Direct ByteBuffer API Key: HADOOP-10047 URL: https://issues.apache.org/jira/browse/HADOOP-10047 Project: Hadoop Common Issue Type: New Feature Components: io Reporter: Gopal V Assignee: Gopal V
With the Zero-Copy reads in HDFS (HDFS-5260), it becomes important to perform all I/O operations without copying data into byte[] buffers or other buffers which wrap over them. This is a proposal for adding new DirectCompressor and DirectDecompressor interfaces to the io.compress, to indicate codecs which want to surface the direct buffer layer upwards. The implementation may or may not copy the buffers passed in, but should work with direct heap/mmap buffers and cannot assume .array() availability. -- This message was sent by Atlassian JIRA (v6.1#6144)
