Increasing the number of open file descriptors

Regardless of where you put your Dgraph databases, you should set the hard and soft limits on the number of open file descriptors to 65536, at a minimum.

On each Dgraph node, open /etc/security/limits.conf and set the hard and soft nofile limits to at least 65536:

<bdd>      soft      nofile      65536
<bdd>      hard      nofile      65536

Where <bdd> is the name of the bdd user.
