Ishan Chattopadhyaya commented on SOLR-11920:
---------------------------------------------
Thanks for looking at this.
bq. .. local copy instead of the hard link approach ...
Need to verify if this works on Windows. If not, maybe move could also work
here?
bq. Maybe we should turn the two INFO log lines into DEBUG? I know they are
currently INFO as well but seems like we should change it
I'm fine either ways. On the field, I've found this to be helpful information
looking at logs from production servers. Though, if you insist, I'm okay with
making them DEBUG.

> In the case of fullCopy=true, all files are copied over from the
> leader/master irrespective of whether or not that exact file exists with the
> replica/slave. This is wasteful, esp. in tlog replicas or pull replicas, when
> only a fraction of the total files are different.
> This stems from SOLR-11815.
