thoughts and code of my bachelor thesis: distribute graphity

bachelor-thesis's Issues

redefine cluster

The controller script needs a command that can change the cluster IP address range when nodes were added/removed from the cluster.

Example usage:

$>cluster <network> <numNodes>
$>cluster 192.168.0 32

Circus daemon control

The controller script requires Circus to be running.
Some actions require that the daemon has to be restarted and we would have to start it on system startup. Thus we need two commands

• init and
• shutdown

in the controller to manage the Circus daemons via parallel SSH.

Fix locking of Graphity ego network

Lock the followers of a user on post

Move thoughts to wiki

Separate code and thoughts/tutorials

create circus configuration

The cluster control page mentions and lists the circus configuration.
At the moment there is no such configuration and the block is a dummy.
It has to be created and inserted into the page afterwards.

circus arbiter start/stop

The controller script supports to start/stop a certain watcher.
A comfortable feature would be to start/stop all watchers at once.
This feature has to be implemented.

Example usage:

$>start

create pull request for circus documentation

According to my tutorial:

Add new command

1. add missing import statements
2. add message example

Circus library

1. add module import hints

Configuration file templates

Create configuration file templates, document where they are put, update the paths in the configure command of circus and describe the process of transmitting new templates to the cluster.

Neo4j & Graphity plugin

Add Neo4j to unikonode 1 together with the Graphity plugin and document the process of installing the plugin.

custom circus command (configure)

A custom circus command named configure has to be created, that configures both

• Neo4j and
• Titan

on the respecitve node, according to its IP address. The address wil be part of the command along with the addresses of all nodes forming the current cluster.
It has to be linked and documented on the cluster control page when implemented.

Example usage:

$>configure

Titan: Graphity extension

Add the Graphity extension to unikonode 1 and document the process of

• Extension file installation
• Rexster configuration
