fuzzydata

The fuzzydata Workflow Generator

The fuzzydata workflow generator enables:

• Abstract specification of Dataframe-based Workflows
• Generation of randomized tables and workflows
• Loading and replay of workflows on multiple clients

Fuzzydata is currently designed to run using the following clients:

• pandas
• modin[dask|ray]
• SQLIte

fuzzydata is designed to be extensible, you may implement your own client. Please see the existing clients in fuzzydata/clients for ways to extend the abstract Artifact, Operation and Workflow classes for your client.

Installation

Manual build/install using pip.

pip install fuzzydata

fuzzydata Does not install modin or SQLAlchemy by default, but this can be specified as an install option:

pip install fuzzydata[modin|sql|all]

Usage

Some examples of fuzzydata usage are in the examples directory. You can also run the fuzzydata command to get a list of command-line options supported in fuzzydata

$ fuzzydata --help
usage: fuzzydata [-h] [--wf_client WF_CLIENT] [--output_dir OUTPUT_DIR] [--wf_name WF_NAME]
              [--columns COLUMNS] [--rows ROWS] [--versions VERSIONS] [--bfactor BFACTOR]
              [--matfreq MATFREQ] [--npp NPP] [--log LOG] [--replay_dir REPLAY_DIR]
              [--wf_options WF_OPTIONS] [--exclude_ops EXCLUDE_OPS] [--scale_artifact SCALE_ARTIFACT]

optional arguments:
  -h, --help            show this help message and exit
  --wf_client WF_CLIENT
                        Workflow Client to be used (Default pandas). Available Workflows: pandas|modin|sql
  --output_dir OUTPUT_DIR
                        Location of Output datasets to be stored
  --wf_name WF_NAME     prefix for each workflow to be generated dir to be the path prefix for these files.
  --columns COLUMNS     Number of columns in the base version
  --rows ROWS           Number of rows in the base version
  --versions VERSIONS   Number of artifact versions to generate
  --bfactor BFACTOR     Workflow Branching factor, 0.1 is linear, 100 is star-like
  --matfreq MATFREQ     Materialization frequency, i.e. how many operations before writing out an artifact
  --log LOG             Set Logging Level
  --replay_dir REPLAY_DIR

  --exclude_ops EXCLUDE_OPS
                        JSON-encoded list of ops to exclude e.g. ["pivot"]
  --scale_artifact SCALE_ARTIFACT
                        JSON-encoded dict of {artifact_label: new_size} to be scaled up e.g. {"artifact_0"
