Yi Liu updated HADOOP-11961: ---------------------------- Description: (was: Today, we have a discussion including [~zhz], [~drankye], etc., also discuss in HDFS-8347. Some coder like {{RS}} and {{XOR}} is linear, some have coding boundary like HitchHicker. If the coder is linear, we can decode at any size, and we don't need to padding inputs to *chunksize*, if the coder is not linear, the inputs need to padding to *chunksize*, then do decode. This interface is important for performance, and can save memory/disk space since the parity cells are the same as first data cell (less than codec chunksize). ) Assignee: (was: Yi Liu) Summary: Add interface of whether codec has chunk boundary to Erasure coder (was: Add isLinear interface to Erasure coder) > Add interface of whether codec has chunk boundary to Erasure coder > ------------------------------------------------------------------ > > Key: HADOOP-11961 > URL: https://issues.apache.org/jira/browse/HADOOP-11961 > Project: Hadoop Common > Issue Type: Sub-task > Components: io > Reporter: Yi Liu > -- This message was sent by Atlassian JIRA (v6.3.4#6332)
