Subject [jira] [Commented] (ARIES-1565) Performance Improvement: unpack subsystem artifacts to tmp folder to avoid directly reading from zip archive
Date Fri, 12 Aug 2016 22:18:21 GMT

    [ https://issues.apache.org/jira/browse/ARIES-1565?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15419596#comment-15419596

Wouter Bancken commented on ARIES-1565:
---------------------------------------

[~jwross@us.ibm.com]
Good to know there were actual errors and it wasn't an issue on my part. It was my first change
to the Aries codebase so I wasn't sure. 

As for the error, I'd suggest you take the lead on this? We included the change in subsystems
to avoid touching aries-utils as you suggested. Avoiding the import package seems possible
on first sight but it means we'll be including more of aries-utils in subsystems and I don't
know if that's desirable.

> h4. Description
> Aries copies ESA archives to a temporary zip file during the installation phase. Afterwards,
bundles are read directly from this temporary zip which has a large impact on the startup
performance of Aries applications. By unpacking the esa artifact into the temporary folder
it is unpacked only once. Subsequent reads for the bundles (jars) can be read directly from
the folder.
