"Python lightweight, plugin based, data analysis engine"

Project description

Software chunks initially developped for ID02 upgrade program in 2012-2014.

Dahu is a lightweight plugin based framework…

… technically a JSON-RPC server over Tango:

  • plugins can be class or can be generated from any state-less function written in Python

  • a plugin is executed within a job, each job lives in its own thread.

  • plugins have empty constructors plus 4 methods (or more)

  • setup allows to set the input parameters. Sanitization is performed here.

  • process does the work.

  • teardown sets the output, the logging and cleans up (if needed).

  • abort can be used to stop the processing if a plugin is a daemon.

  • the job is responsible for serializing on disk of the plugin’s input and output

  • jobs can be launched using the tango interface (or other …)

  • plugins have a single input and output, they are simple JSON-serializable dictionaries.
