> S3AInputStream.skip() to use lazy seek
> --------------------------------------
>
> Key: HADOOP-15245
> URL: https://issues.apache.org/jira/browse/HADOOP-15245
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.1.0
> Reporter: Steve Loughran
> Priority: Major
> Labels: pull-request-available
> Time Spent: 50m
> Remaining Estimate: 0h
>
> the default skip() does a read and discard of all bytes, no matter how far
> ahead the skip is. This is very inefficient if the skip() is being done on
> S3A random IO, though exactly what to do when in sequential mode.
> Proposed:
> * add an optimized version of S3AInputStream.skip() which does a lazy seek,
> which itself will decided when to skip() vs issue a new GET.
> * add some more instrumentation to measure how often this gets used
