Hello everyone, Will it matter configuring some 'x' number of shards per index, if I am using single instance/node of elastic search. I have a single box that has elastic search instance on it (no cluster). Will it have any implications, when using default 5 (or maybe just 1) shards per index? Creating an index with more number of shards without a cluster or more node will help in anyway in terms of performance or scalability? Please advise. Appreciate your inputs!

Not unless you are creating a _lot_ of indies on that node, remember that a shard is a lucene instance and take up a certain amount of resources. Generally it's a good idea to create multiple shards if you expect to add more nodes, that way it's easier to spread the data across the new nodes without having to reindex. But for dev purposes on a single node, having a single shard index is fine.

Appreciate your input Mark. So my understanding was correct, that on a single node (without cluster) having single shard per index will work almost the same as having default 5 shards per index.
