Hi all, 📢 RFC Announcement: Broker and Server Segment Query Cache for Apache Pinot Under the guidance of Pinot PMC Xiangfu, we’re proposing a two-layer query cache for Apache Pinot: 1️⃣ Broker Result Cache – caches fully merged query results. 2️⃣ Server Segment Result Cache – caches per-segment partial results (aggregations, group-bys, selections). By storing reusable results in Query Cache, this feature can cut redundant computation and scanning, significantly reducing latency and cost—especially for high-concurrency workloads on large datasets. 📄 Pinot Issue: https://github.com/apache/pinot/issues/16584 📝 Design Doc: https://docs.google.com/document/d/1qUjLEJnhODD3oJrOP_Q15JP-Tb4RkLLNyDHYaWcztMg/edit?usp=sharing 💬 Discussion Channel: https://app.slack.com/huddle/TDR79RQN8/C09A97SDMTN If you’re interested, please comment in the design doc or join the discussion channel.
