How We Reduced Median Memory Estimation Error by 99%, With the Help of AI

2026-06-01

Mixpanel's compaction pipeline faced issues with memory estimates, leading to Out Of Memory errors and inefficiencies due to a simplistic multiplier model. By replacing this with a "last observed value" approach, further refined through AI-assisted large-scale analysis, the median memory estimation error was reduced by 99%, significantly boosting production reliability.
