Hi， I feel very confuse when deciding the number of primary shards at beginning.
As we know the number of shards and replicas can be defined per index at the time the index is created. After the index is created, we may change the number of replicas dynamically anytime but we cannot change the number of primary shards after-the-fact. Our ES project may be run as trial version at beginning an it is only 10 machines in cluster. However, if the project run in production environment, the machine magnitude must increase and there will have 200 or more machines. How can we decide shards number at beginning? Is it encourage to run 400 or more shards in 10 machines, will it reduce the performance of cluster? Thank you for reading and look forward to your suggestions. -- Please update your bookmarks!
