> Improve getInputSummary
> -----------------------
>
> Key: HIVE-21071
> URL: https://issues.apache.org/jira/browse/HIVE-21071
> Project: Hive
> Issue Type: Improvement
> Components: HiveServer2
> Affects Versions: 4.0.0, 3.2.0
> Reporter: BELUGA BEHR
> Assignee: BELUGA BEHR
> Priority: Major
> Attachments: HIVE-21071.1.patch, HIVE-21071.2.patch,
> HIVE-21071.3.patch, HIVE-21071.4.patch, HIVE-21071.5.patch,
> HIVE-21071.6.patch, HIVE-21071.7.patch, HIVE-21071.8.patch, HIVE-21071.9.patch
>
>
> There is a global lock in the {{getInptSummary}} code, so it is important
> that it be fast. The current implementation has quite a bit of overhead that
> can be re-engineered.
> For example, the current implementation keeps a map of File Path to
> ContentSummary object. This map is populated by several threads
> concurrently. The method then loops through the map, in a single thread, at
> the end to add up all of the ContentSummary objects and ignores the paths.
> The code can be be re-engineered to not use a map, or a collection at all, to
> store the results and instead just keep a running tally. By keeping a tally,
> there is no {{O\(n)}} operation at the end to perform the addition.
> There are other things can be improved. The method returns an object which
> is never used anywhere, so change method to void return type.
