Month: 2025-04 Overview: Focused on strengthening the reliability and responsiveness of admin RPC webhook delivery for transaction stream data in XRPLF/rippled. Delivered a targeted improvement to webhook handling that prevents dropped transaction notifications on large ledgers and shortens end-to-end latency, enabling more timely and reliable notifications. Key deliverable: Webhook Delivery Reliability for Transaction Stream Data - What was delivered: Removed a hardcoded webhook queue limit and reduced the HTTP RPC timeout from 10 minutes to 30 seconds for admin RPC webhook delivery. This directly addresses notification drops on large ledgers and improves overall system responsiveness. Commit reference: aafd2d85251d760bb00862945b9c10556181231b (Fix: admin RPC webhook queue limit removal and timeout reduction, #5163). - Repository: XRPLF/rippled Impact: Improves reliability and responsiveness of transaction notifications, reducing dropped events and wait times for administrators and downstream systems. Technologies/Skills demonstrated: admin RPC, webhook architecture, queue management, timeout tuning, performance optimization, change tracing through commit #5163. Overall accomplishments: A targeted, low-risk change with high business value by stabilizing the notification pipeline for large ledgers, improving visibility and responsiveness for admins and downstream consumers. Next steps / considerations: Monitor webhook delivery success rates and latency, validate in staging against large ledger loads, and consider configurable or adaptive queue sizing if ledger characteristics vary widely.
