Guide to the Wukong Toolkit

• Wukong: data flows and job flows

  • concepts -- fundamental concepts and data models
  • wukong-workflow -- Workflow definition
  • wukong-dataflow -- Dataflow definition
  • wukong-mapred -- Write mapreduce jobs using wukong transforms; debug them on your laptop, run them in Hadoop
  • wukong-widgets -- Common data transforms
  • wukong-fs -- Read and manipulate files on local, hdfs (jruby or thrift), s3n or s3hdfs filesystems using the standard ruby File interface.
  • wukong-flume -- Flume flow configuration and wukong-streamer flume decorators
  • references -- Further reading
  • PDF with dataflow and workflow graphs; original .graffle file

• Hanuman: Elegant small graph assembly

  • models -- graph, stage, event
  • binding -- bind graph to resources, execute it
  • graphdot -- express graph as .dot (graphviz) format, and thusly PNG or SVG.
  • canvas -- view and edit a hanuman graph from your browser

• Swineherd: Common interface on ugly tools

  • commander -- Turn readable hash into safe commandline (param conv, escaping) does this go in configliere?
  • launcher -- Execute command, capture stdin/stderr
  • reporter -- Summarize execution with a viacondios-able hash
  • mixins -- Java, gnu-style, has_input/output
  • template -- template scripts with configliere variables
  • apps -- Hadoop, pig, flume; ?? cp, mv, rm, zip, tar, bz2, gz, ssh, scp ??

• Gorillib: minimal-dependency core language modification and low-level toolkit. Fine-grained control over what is loaded.

  • core -- indispensible improvements to the core language, metaprogramming support, and broadly-useful convenience methods.
  • path_helpers -- path_to, autoload_paths (like $PATH)

• go-model structures

  • model -- lightweight structured object definition
  • bucket -- full-featured structured object definition
  • builder -- builder (dsl-style) model definition
  • deep_hash
  • model/overlay
  • collection
  • factories
  • icss -- construct structured object from schema

• Configliere: Manage settings

  • commandline -- read settings from commandline params
  • command -- git-style executables; provide multiple commands (including scoped options)
  • layer -- Project settings through a late-resolved stack of config objects. Intended to solve the 'patch the config for test/dev/prod', the 'only some config variables apply for this command, some apply for this other one', and the 'organization / cloud / cluster / facet / server' problems

• Vayacondios: data goes in, the right thing happens. Universal routing of facts, configuration and metrics throughout the organization.

  • server -- receive events via HTTP, websockets, flume, or UDP (statsd), and make simple constrained queries.
  • configliere -- transparently syndicate configuration through configliere
  • notifications. -- an activesupport/notification observer
  • triggers -- plug in any wukong transformer to manipulate events upon receipt
  • workers -- collection of small daemons that pull in truth, scheduled or on-demand.
  • backend -- mongo; cube; activity stream

• Ironfan: System Diagram come to life

  • models -- cluster, facet, server, machine, component, aspect, announcement. Use configliere/layer and gorillib/dsl_model.
  • knife plugins --
  • silverware -- discovery and aspect slicing
  • pantry -- cookbooks
  • ci --
  • chimpstation -- set up a workstation
  • homebase -- organizes all of it

• Goliath + SenorArmando:
