Buckets

Buckets are containers for tables in Storage. They are further organized into the following three stages:

  1. in — for input data (usually extractor results)
  2. out — for processed data (usually results of transformations or applications)
  3. sys — deprecated stage used for configuration of some components

The distinction between the input and output stage is purely conventional differentiation between raw and processed data. When creating a new bucket, select one of the stages and a suitable database backend based on its properties. For information on how to load data into Storage, see the corresponding part of our tutorial.

Apart from being used for organizing tables, buckets can also be used for sharing tables.
