Interesting - 9.4 has been out there since October, I'm surprised no one
reported this earlier.  But I guess there's always a lag for teams to
upgrade to new versions...

Is the number of "expensive" tasks configurable, such that there's a
workaround for collections with many shards?  Assuming not, this does sound
serious enough to "fail" the VOTE as it'd mean that backup/restore is
essentially broken for sufficiently large collections.

In terms of SOLR-16879 - any chance you're willing to work on a fix Pierre?

Best,

Jason
