We are investigating stability issues we encounter in our ES cluster, and feel that the ES documentation is lacking import information on this topic.
The mailing list seems to fill the gap with the "Document about recommended hardware specs & sharding/index strategy" http://elasticsearch-users.115913.n3.nabble.com/Recommended-Hardware-Specs-amp-Sharding-Index-Strate... The information in this conversation looks important (for example shards should not be bigger then the heap size and the heap size shoud be half of the total memory) but we haven’t found this information in the documentation. We have two questions: * Did we overlook this in the official documentation? * If the official documentation is lacking this important information, what should we do to make this taken care of?
