> We don't recommend having shards over 50GB as it just makes reallocation harder than it should be. You can probably go larger if you only have a single node, but don't forget that to change the number of shards for an index, you need to reindex that entire index.
Thanks for your answer!
There also some viewpoints show that we should keep shards number per node small.
Like this answer : [Redirecting to Google Groups](https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!topic/elasticsearch/hrq_z2qtNmo)
and this experiment : [Trifork Blog - Keep updated on the technical solutions Trifork is working on!](http://blog.trifork.com/2014/01/07/elasticsearch-how-many-shards/)
How can I keep balance between “light and easy to reallocation” and “more shard use more resource”？

@shinyke - When u have say shards of max size 50 G, you are talking about shards say 10 for .5 TB of data. 10 is not big. Remember u do have limit per node (depends on ur query/index characteristics) on how much data u can have in a node to effectively suppoer queries with a reasonable performance.
btw - my .5 TB of data is an example!
