API Endpoints - Read-only - XCOM

[mik-laj]

Description

Hello

We need to create several endpoints that perform basic read-only operations on XCOM . We need the following endpoints:

• GET /dags/{dag_id}/taskInstances/{task_id}/{execution_date}/xcomValues
• GET /dags/{dag_id}/taskInstances/{task_id}/{execution_date}/xcomValues/{key}

For now, we focus only on read-only operations, but the others will also be implemented as the next step.

Detailed information is available in the issue:

Hi @mik-laj would be keen on working on this issue!

Thanks. For now, we're focusing on read-only endpoints. We need to build a scheme using Marshmallow compatible with OpenAPI. Soon I will write more information on Slack - #sig-api channel.
