Description
I recently did some performance test work for the mongodb tools in sharded clusters and hit a few snags that might have been avoided with some additional documentation; in particular:
1. I didn't realize from the documentation at http://docs.mongodb.org/manual/tutorial/shard-collection-with-a-hashed-shard-key/ that you do not need to perform a manual split and move of chunks when you're using hash based sharding. Also, the documentation section in "Sharded Cluster Data Management", while detailed, could be hard to follow for new users.
2. I looked around our documentation but couldn't find a step-by-step guide (and the necessary caveats) of how one might go about loading data into sharded cluster e.g. using mongorestore/mongoimport. I imagine this will be a very common use case for new MongoDB users and those who want to experiment with sharded cluster setup/performance.
Perhaps including an end-to-end example of how all the sub-sections tie together for practical tasks (e.g. a real-world use case) would be of additional help.
