Todd Lipcon resolved HADOOP-8258. --------------------------------- Resolution: Duplicate Resolving as dup - please see HADOOP-8148. > Add interfaces for compression codecs to use direct byte buffers > ---------------------------------------------------------------- > > Key: HADOOP-8258 > URL: https://issues.apache.org/jira/browse/HADOOP-8258 > Project: Hadoop Common > Issue Type: New Feature > Components: io, native, performance > Affects Versions: 3.0.0 > Reporter: Todd Lipcon > > Currently, the codec interface only provides input/output functions based on > byte arrays. Given that most of the codecs are implemented in native code, > this necessitates two extra copies - one to copy the input data to a direct > buffer, and one to copy the output data back to a byte array. We should add > interfaces to Decompressor/Compressor that can work directly with direct byte > buffers to avoid these copies. -- This message is automatically generated by JIRA.
