Mar 1, 2026

March 2026 monthly summary for gooddata/gooddata-python-sdk focusing on feature delivery and bug fixes in filtering capabilities. Delivered cross-model filtering enhancements and API client support for new filter types, aligned with backend changes (CQ-2005). Regenerated API client to expose ArbitraryFilter and MatchAttributeFilter in queries, and updated converters across compute, visualization, and ExecutionContext. Result: richer, more flexible data querying and improved developer experience.

Nov 1, 2025

November 2025: Delivered key stability and compatibility improvements across two repos, with enhancements that drive reliability, developer productivity, and downstream data pipelines. Notable outcomes include restoring GeneratorStream support for Tables and RecordBatchReaders in Arrow, adding InlineFilter handling in the Compute-to-SDK converter, and relaxing uv version constraints to reduce upgrade friction. All changes were validated via CI/tests, with no user-facing regressions. Business impact includes reduced risk of data-pipeline outages, expanded data-processing scenarios, and improved maintenance ease for downstream consumers.

September 2025

Sep 1, 2025

In Sep 2025, delivered regeneration of the GoodData Python SDK API client to align with the latest GoodData API specifications. This included updating models and endpoints and introducing updated automation capabilities (workspace automation, organization automation, and validation endpoints). The work ensures API compatibility for downstream integrations and reduces maintenance burden for SDK consumers.

June 2025

5 Commits • 2 Features

Jun 1, 2025

June 2025: Delivered targeted API enhancements in the gooddata-python-sdk that improve execution lifecycle handling, type safety, and resource management. Key work focused on making execution results available earlier, simplifying data access types, and enabling safer cancellation for long-running executions.

May 2025

14 Commits • 6 Features

May 1, 2025

May 2025: Delivered major enhancements across Python and UI SDKs, focusing on asynchronous task management, enhanced execution metadata, and API client alignment. Implemented FlexConnect DataSourceMessages and ExecutionResultMetadata support, added robust polling and distinct invocation types for long-running tasks, extended the Execution API with cancellation, proper exports, and improved error handling, and aligned UI SDK data models with backend metadata through Tiger API client regeneration and backend metadata propagation.

April 2025

4 Commits • 2 Features

Apr 1, 2025

April 2025: Delivered key reliability and observability improvements across Python SDK and UI SDK, focusing on business value and developer experience. Implemented a critical bug fix in ComputeToSdkConverter to correct ranking filter dimensionality handling, added regression tests, and enhanced error reporting and tracing in the UI SDK with a feature flag for rich datapoint errors. Also introduced an alpha onDataView callback for visualization components to support reactive data loading. These changes reduce debugging time under heavy data loads and lay groundwork for safer, observable analytics workflows.

March 2025

7 Commits • 4 Features

Mar 1, 2025

March 2025 performance summary: Delivered major enhancements to export workflows in both Python SDK and UI SDK, including raw and slides export capabilities, execution settings propagation, and customization options. Regenerated API clients to align with new endpoints; refined export metadata naming; introduced UI-consistent overrides for dashboard exports; and ensured derived measures titles are correctly displayed. These efforts deliver richer export functionality, improved automation, and better alignment with UI, directly enabling customers to automate reporting and customize exports with reduced integration cost.

November 2024

6 Commits • 1 Features

Nov 1, 2024

November 2024 monthly highlights focusing on delivering FLEXCONNECT rollout and FLIGHTRPC migration in the UI SDK, along with a targeted Python SDK improvement to fix type safety for ExecutionContextFilter. The work enhances data-source scalability, reduces migration risk, and demonstrates solid API maintenance and cross-language integration. Key outcomes include: streamlined data-source surface, aligned backend/frontend naming, and prepared groundwork for future migrations and credential-based access.
