A distributed key-value store built to make use of various Mix and OTP features including Tasks, Agents, GenServers, and umbrella applications.
The application is meant to run on at least two separate nodes simultaneously, so to start it up you'll need to run startup commands in at least two separate terminal windows or on two different machines that are on the same network.
We'll run one startup command from the root directory, which will start up
a TCP server, and a second command from the apps/kv subdirectory to handle
some of those TCP requests (the server process itself will also handle some
requests).
You can start the application via iEx with iex --sname some_name -S mix,
where you have replaced some_name with different arbitrary names of your choosing
for each terminal window/machine
For example, because I'm big nerd who likes to watch Noam Chomsky debate Michel
Foucault on YouTube I start the application on my laptop by running iex --sname chomsky -S mix from the root directory in one terminal window, and iex --sname foucault -S mix
in a second window from the apps/kv directory.
Connect one or more TCP clients to 127.0.0.1:4040 to test the application out.
Eg telnet 127.0.0.1 4040.
This key-value store allows you to create buckets, and to get, set, and delete key-value pairs within buckets. Valid (case-sensitive and whitespace-sensitive) commands are:
CREATE bucket_name
SET bucket_name key value
GET bucket_name key
DELETE bucket_name key
Includes tests written with ExUnit. You can run the test suite with mix test.
The unit test for KV.Router expects multiple nodes running this application
to be connected. You can run this test successfully by starting the application
on at least one machine or terminal window before running the tests with the
command elixir --sname some_name@my-computer-name -S mix test.
