> Key: BEAM-13170
> URL: https://issues.apache.org/jira/browse/BEAM-13170
> Project: Beam
> Issue Type: Improvement
> Components: cross-language, website
> Reporter: Chamikara Madhusanka Jayalath
> Priority: P2
> Labels: stale-P2
>
> Currently documentation regarding how language specific types map to Beam schema types and vice versa are scattered in different locations.
> For example,
> * Following describes how Python types map to Beam schema types.
> [https://beam.apache.org/releases/pydoc/2.32.0/apache_beam.typehints.schemas.html]
> * Beam Programming Guides gives some details regarding types and few examples but this seems to be incomplete.
> [https://beam.apache.org/documentation/programming-guide/#schemas]
> * Following has a table that describes how types from various languages relate to each other.
> [https://docs.google.com/document/d/1uu9pJktzT_O3DxGd1-Q2op4nRk4HekIZbzi-0oTAips/edit#bookmark=id.tlciv62z2d9u]
> * There's limited documentation on using Python NamedTupes to properly create Beam Rows.
>
> Ideally, we should extend the Beam Programming Guide (or create a new guide) to describe currently supported Schema types and how types from various SDK languages map to such types. We should also have enough examples to illustrate the usage.
