Mike Drob commented on SOLR-13990:
----------------------------------
According to the author of both woodstox and alto, the latter is 50-100%
faster, so that's a pretty big jump I think.
Also, looks like the failure shared by Dawid is related to this still open
issue https://github.com/FasterXML/aalto-xml/issues/65 from over a year ago,
and is similar to the issues brought up in the Hadoop JIRA that sparked their
migration as well. I think Anshum is traveling but I'm looking into this for as
much time as I have until he gets back.
[~dweiss] - do you want to do the revert so that we're not waiting for Anshum
to come back? Or I can do it if you're busy with other things right now.
