/v0/pipelines?selector=status Includes Error Messages In The Response Body

Introduction

When working with APIs, it's essential to consider the efficiency of data retrieval, especially when dealing with large datasets or complex queries. In this article, we'll discuss a proposed solution to optimize API responses for the /v0/pipelines?selector=status endpoint, which currently includes error messages in the response body.

The Problem

The Rust and SQL compiler messages can get lengthy, which eats up a lot of bandwidth when polling this endpoint. This can lead to performance issues and increased latency, making it challenging to retrieve data efficiently. The proposed solution aims to address this issue by returning specific fields with an empty object {} as a value when they are not null.

The Proposed Solution

The proposed solution involves modifying the API response to include the following fields with an empty object {} as a value when they are not null:

• sql_compilation
• rust_compilation
• system_error

This makes the response compatible with the ?selector=all body while omitting details not expected in a ?selector=status endpoint. By doing so, we can reduce the amount of data transferred and improve the overall performance of the API.

Example Response Body

Here's an example response body that demonstrates the proposed solution:

[
    {
        "id": "01968c7c-3052-7831-93e1-150789495681",
        "name": "fraud-detection",
        "description": "Tackle fraud-detection using a real-time feature engineering pipeline in SQL.",
        "created_at": "2025-05-01T15:34:31.250288Z",
        "version": 2,
        "platform_version": "0.47.0",
        "program_version": 2,
        "program_status": "Success",
        "program_status_since": "2025-05-01T15:56:18.162912Z",
        "program_error": {
            "sql_compilation": {},
            "rust_compilation": {
                "exit_code": 0,
                "messages": []
            },
            "system_error": null
        },
        "deployment_status": "Shutdown",
        "deployment_status_since": "2025-05-01T16:49:08.732984Z",
        "deployment_desired_status": "Shutdown",
        "deployment_error": null,
        "refresh_version": 3
    },

Benefits of the Proposed Solution

The proposed solution offers several benefits, including:

• Improved performance: By reducing the amount of data transferred, we can improve the overall performance of the API and reduce latency.
• Increased efficiency: The proposed solution allows for more efficient data retrieval, making it easier to retrieve the data needed without unnecessary overhead.
• Simplified API responses: By omitting details not expected in a ?selector=status endpoint, we can simplify API responses and make them easier to consume.
