Hi SOLR Community, I've been investigating SOLR 8 and recovery behavior. From what I can tell, older SOLR versions (6 and before at least) required a solrdata drive with at least 2x the space of the index; so an index which could be up to 100GB on one shard would require a disk with at least 200GB of storage space, since recovery would copy a brand new index over and then switch after the fact.
However, SOLR 8 looks to have a different behavior wherein the index is perhaps updated in place, and thus a 100GB / shard index might only need a bit more headroom (call it 110GB say). Is this always the case with recovery on SOLR 8+? Or are there some situations where you might need 200GB for the recovery? Thanks in advance! Stephen
