Description
Firstly, As of today we cannot create an empty collection from SolrJ
I have a two node cluster and this API call fails with an error
//Create a coreless collection of 3 shards CollectionAdminRequest.Create create = CollectionAdminRequest .createCollection("test_collection", "conf1", 3, 0) .setCreateNodeSet(OverseerCollectionMessageHandler.CREATE_NODE_SET_EMPTY) .setMaxShardsPerNode(-1);
Secondly if I use the API directly , {{http://localhost:8983/solr/admin/collections?action=create&name=test_coll&numShards=5&createNodeSet=EMPTY }}the state.json has replicationFactor = nrtReplicas = 1 instead of 0
"test_coll":{ "pullReplicas":"0", "replicationFactor":"1", "router":{"name":"compositeId"}, "maxShardsPerNode":"1", "autoAddReplicas":"false", "nrtReplicas":"1", "tlogReplicas":"0", "shards":{ "shard1":{ "range":"80000000-b332ffff", "state":"active", "replicas":{}}, "shard2":{
On a side note , I think we should rethink how replicationFactor/nrtReplicas/tlogReplicas/pullReplicas are stored.
These values could be stored at a per shard level such that adding a replica will actually refelct the total replication count
