Hello, We are running Solr 7.2.1 and planning for a deployment which will grow to 4 billion documents over time. We have 16 nodes at disposal.I am thinking between 3 configurations:
1 cluster - 16 nodes vs 2 clusters - 8 nodes each vs 4 clusters -4 nodes each Irrespective of the configuration, each node would host 8 shards (eg: a cluster with 16 nodes would have 16*8=128 shards; similarly, 32 shards in a 4 node cluster). These 16 nodes will be hosted across 4 beefy servers each with 128 GB RAM. So we can allocate 32 GB RAM (not heap space) to each node. what configuration would be most efficient for our use case considering moderate-heavy indexing and search load? Would also like to know the tradeoffs involved if any. Thanks in advance! Regards, Rahul
