You can / should create different collections for different client data, so that you can for surely improve performance as per need. There are multiple configurations which drives indexing and querying capabilities and incorporating everything in single collection will hinder that flexibility. Also if you need to add new client in future, you don't need to think about sharding again, add new collection and tweak its configuration as per need. Still if you need to use compositeKey to acheive your use-case, I am not sure how to do that honestly. Since shards are predefined when collection will be created. You cannot add more shards and such. You can only split a shard, which will divide the index and hence the hash range. I will strongly recommend you to reconsider your SolrCloud design technique for your use-case.
