Jun 1, 2025June 2025 performance summary for dagster-io/dagster: Delivered two impactful updates that improve data accuracy and observability with direct business value. Fixed an off-by-one bug in Insights Details Dialog bucket logic to ensure hourly activity charts reflect the correct window. Introduced an automated Random Asset Sampling Job with a 15-minute cadence to populate time-to-resolution metrics by sampling three random assets per interval. These changes enhance dashboard reliability, reduce data gaps, and enable faster MTTR analysis for product and engineering decisions. Technologies demonstrated include Python scheduling, cron-like job orchestration, and robust time-window calculations, with commits 8bded2881cc9f22906428dc7d37973c606980cf2 and f8abf1544b868a48f7b1935aa4293be6ba6d5fda.

Oct 1, 2024Month: 2024-10 — Focused on stabilizing the dynamic partitions asset wipe path in dagster. A targeted bug fix ensures wipe operations correctly retrieve partition keys by passing the dynamic partitions store to get_partition_keys_in_range, reducing risk of incomplete wipes and data inconsistencies. This work reinforces asset lifecycle reliability under dynamic partition scenarios and aligns with our commitment to data integrity.
