In Solr, the default maxShardsPerNode is one shard per node. In this setup, we had 3 nodes, so we should not attempt to add more replicas to a collection (e.g., numShards=2 & replicationFactor=2 will result in four shards in total spreaded across three nodes).. Solr supports distributed indexing (routing) in its true form only in the SolrCloud mode. In the legacy distributed mode, Solr does not calculate universal term/doc frequencies. For most large-scale implementations, it is not likely to matter that Solr calculates TF/IDF at the shard level. Soft commit is about visibility, and my assumption here is that bulk indexing isn't about near real time.

Solr sharding involves splitting a single Solr index into multiple parts, which may be on different machines. When the data is too large for one node, you can break it up and store it in sections by creating one or more shards, each containing a unique slice of the index. Sharding is important for two primary reasons:. The standard procedure for scaling Lucene/Solr is as follows: first, maximize performance on a single machine. Next, absorb high query volume by replicating to multiple machines. If the index becomes too large for a single machine, split the index across multiple machines (or, shard the index).
