With thanks to http://superuser.com/a/1171026/39144

It seems like there is an entirely different method for changing the open files limit for each version of OS X! For OS X Sierra (10.12.X) you need to:

1. In /Library/LaunchDaemons create a file named limit.maxfiles.plist and paste the following in (feel free to change the two numbers (which are the soft and hard limits, respectively):

'''Pexpect is a Python module for spawning child applications and controlling
them automatically. Pexpect can be used for automating interactive applications
such as ssh, ftp, passwd, telnet, etc. It can be used to a automate setup
scripts for duplicating software package installations on different servers. It
can be used for automated software testing. Pexpect is in the spirit of Don
Libes' Expect, but Pexpect is pure Python. Other Expect-like modules for Python
require TCL and Expect or require C extensions to be compiled. Pexpect does not
use C, Expect, or TCL extensions. It should work on any platform that supports
the standard Python pty module. The Pexpect interface focuses on ease of use so
that simple tasks are easy.

MessageHub is Kafka

Kafka/MessageHub is a distributed log. It scales writes via partitioning data. You can write a custom partitioner, though the DefaultPartitioner is often sufficient for most applications.

The DefaultPartitioner uses the message key to determine which partition to write a message. This allows control of where messages are written (important for ConsumerGroups…). This also means that Kafka is susceptible to hot partitions, where more messages are being routed to a partition than can be supported by the disk IO of the Kafka nodes hosting
