Are you using DocValues for your facet fields? What is the approximate number of unique values in your facets and what is their type (string, number...)? Can you give us a sample request that leads to an OOM? > What will be correct approach here, creating 4 shards with 64 gb ram each or > creating 8 shards with 32 gb ram each? Faceting can result in CPU/memory heavy single-threaded calls in Solr when there are a lot of documents. If your main performance problem is latency, go for the 8 shard solution to let more CPUs work at the same time. If you just need to maximize throughput, the difference should not be that big. - Toke Eskildsen
