Are you using the implicit router? Otherwise you cannot delete a shard. And you won’t have any shards that have zero documents anyway.
It’d be a little convoluted, but you could use the collections COLSTATUS Api to find the names of all your replicas. Then query _one_ replica of each shard with something like solr/collection1_shard1_replica_n1/q=*:*&distrib=false that’ll return the number of live docs (i.e. non-deleted docs) and if it’s zero you can delete the shard. But the implicit router requires you take complete control of where documents go, i.e. which shard they land on. This really sounds like an XY problem. What’s the use case you’re trying to support where you expect a shard’s number of live docs to drop to zero?
