Feb 1, 2026February 2026 (2026-02) monthly summary for rill: Focused on reliability improvements by hardening transient-failure handling. Delivered a critical fix to retry logic by adding 'Connection refused' to the default error matches, significantly reducing failed operations during transient network issues. The change was implemented in repo rilldata/rill and accompanied by updates to docs and AI instructions. Impact includes fewer retry-induced failures, smoother operation under transient conditions, and improved developer guidance. Skills demonstrated include robust error handling patterns, retry strategy design, cross-team collaboration for docs, and attention to release notes.

Dec 1, 2024Month: 2024-12 (rilldata/rill) - Performance/Delivery Summary Key features delivered: - Athena Connector: AWS STS AssumeRole support enabling cross-account access for Athena connections. Introduces RoleARN, RoleSessionName, and ExternalID configuration; credentials are loaded via AssumeRoleProvider when provided. Commits: bcea00b2be1b180d79ce448bc4aedde02d80e30b (#6212). - ClickHouse Incremental Update Strategies: PartitionOverwrite and Merge. Adds IncrementalStrategyPartitionOverwrite for partition-level replacement and a Merge strategy using ReplacingMergeTree for efficient updates, with validation, refined table lookup/creation, and distributed table support. Commits: d3c4c5f41138b679227d56d580e65a4acf054e10 (#6069); 4812c967048edb8f6c0aa498be5729df68e2985d (#6264). Major bugs fixed: - ClickHouse: Fix partition datetime handling and bindvars. Corrects syntax errors in partitions during query execution and adds bindvars for partition values; includes a test validating overwrite functionality with date partitions. Commit: ffc857a6523a88d8b2fedaba2a649d05b8b6660a (#6289). Overall impact and accomplishments: - Security and flexibility: Cross-account Athena access is now straightforward and secure via STS AssumeRole, reducing credential management overhead. - Data freshness and reliability: Incremental update strategies for ClickHouse enable faster, safer partition-level updates and efficient merges, improving data freshness in distributed deployments. - Quality and test coverage: Added tests around date-partition overwrites to prevent regressions and improve maintainability. Technologies/skills demonstrated: - AWS IAM/STS-based credential handling and dynamic credential loading (AssumeRoleProvider) - ClickHouse driver updates for PartitionOverwrite and Merge strategies (Incremental updates, ReplacingMergeTree, distributed tables) - Bind variables usage for partition values and partition datetime handling - Test-driven validation for date-partition overwrites
