Getting started

Creating sources

A source defines the information needed to parse and import a dataset. Sources are referenced when using an Extract block. The source defines the following information:

type of file (delimited, fixed width, json, parquet)
regular expression to match when identifying the file. This will match against the file name
information about headers and footers
specific metadata based on type of file (for csv includes the delimiter etc)

Creating a flow

Running and debugging a flow

Exporting to python code

Configuration

Extending

Creating new block types

Each block type consists of:

Descriptor json
code template
optional code library template
Properties panel
