Hi All, I have been trying to reduce the response time of solr cloud(v8.10, 8 nodes). To achieve this, I have tried increasing the number of shards of solr cloud which can help reduce data size on each shard thereby reducing response time.
I have encountered a few questions regarding sharding strategy: 1. How to decide the ideal number of shards? Is there a minimum or maximum number of shards which should be used? 2. What is the minimum size of a shard after which reducing the size further won't have any effect on the response time (as time taken by other factors like data aggregation will compensate for that) ? 3. Is there some maximum limit to the size of data that should be kept in a shard? As of now we have 8 shards each on a separate node with ~25 gb of data(15-16 million docs) present on each shard. Please advise me of the standard approaches to define the number of shards and shard size. Thanks in advance.
