Hi, Master/Slave concept is not there in SolrCloud, but similar thing we can achive by choosing TLOG + PULL replicas, where writes will happen in TLOG nodes and the PULL replicas gets the updated segments.
Ensure minimum 2 TLOG nodes as PULL replica notes can't became leader of a shard. You can contol the selects to use only PULL replicas by passing shards.preference=replica.type:PULL http://ip:port /solr/indexname/select?q=*:*&shards.preference=replica.type:PULL - Mohandoss.
