---------------------------------
Assignee: Ewan Higgs
> [READ] Implement LevelDBFileRegionFormat
> ----------------------------------------
>
> Key: HDFS-12591
> URL: https://issues.apache.org/jira/browse/HDFS-12591
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: hdfs
> Reporter: Ewan Higgs
> Assignee: Ewan Higgs
> Priority: Minor
> Attachments: HDFS-12591-HDFS-9806.001.patch,
> HDFS-12591-HDFS-9806.002.patch
>
>
> The existing work for HDFS-9806 uses an implementation of the {{FileRegion}}
> read from a csv file. This is good for testability and diagnostic purposes,
> but it is not very efficient for larger systems.
> There should be a version that is similar to the {{TextFileRegionFormat}}
> that instead uses LevelDB.
