> Batch listing of multiple directories
> -------------------------------------
>
> Key: HDFS-13616
> URL: https://issues.apache.org/jira/browse/HDFS-13616
> Project: Hadoop HDFS
> Issue Type: New Feature
> Affects Versions: 3.2.0
> Reporter: Andrew Wang
> Assignee: Andrew Wang
> Priority: Major
> Attachments: HDFS-13616.001.patch, HDFS-13616.002.patch
>
>
> One of the dominant workloads for external metadata services is listing of
> partition directories. This can end up being bottlenecked on RTT time when
> partition directories contain a small number of files. This is fairly common,
> since fine-grained partitioning is used for partition pruning by the query
> engines.
> A batched listing API that takes multiple paths amortizes the RTT cost.
> Initial benchmarks show a 10-20x improvement in metadata loading performance.
