MooseParquet

MooseParquet exports and imports Moose models using Apache Parquet files. It provides a small set of exporters and importers to persist Moose entities, their scalar properties, and their relationships in a tabular graph-oriented format.

Installation

Load MooseParquet with Metacello:

Metacello new
	baseline: 'MooseParquet';
	repository: 'github://moosetechnology/MooseParquet:main/src';
	load.

Example Usage: Export

Export a Moose model to Parquet files:

| model output exporter |

model := MooseModel root anyOne. "get a MooseModel"
output := FileLocator documents / 'exported.moosemodel'.

exporter := MooseParquetExporter new.
exporter model: model.
exporter exportTo: output.

Example Usage: Import

Import the generated Parquet files into a Moose model:

| model input importer |

model := FamixJavaModel new.  "In case of a Java model"
input := FileLocator documents / 'exported.moosemodel'.

importer := MooseParquetImporter new.
importer model: model.
importer importFrom: input.
