From ee6eef2083befc07e46c30807cc11f3a1c38a382 Mon Sep 17 00:00:00 2001 From: jianhong Date: Mon, 4 Aug 2025 23:19:21 +0800 Subject: [PATCH 1/2] feat: implement parallel RPC client for load balancing and improved reliability - Add ParallelRPCClient for managing multiple RPC/API endpoints - Implement round-robin load balancing with automatic health checking - Update CommonApp to support parallel client alongside traditional client - Modify VoteIndexer to use parallel client when available - Add fallback mechanism to traditional sequential health checking - Create parallel-aware API functions for future use - Add comprehensive test coverage for parallel client functionality This implementation reduces data gaps during RPC failover by: 1. Continuously monitoring all endpoint health in background 2. Load balancing requests across healthy endpoints 3. Eliminating sequential health check delays 4. Providing seamless failover without data collection interruption Addresses empty index pointer issues by ensuring continuous data flow even when individual RPC endpoints fail, reducing need for pod restarts. --- internal/common/api/parallel_api.go | 123 ++++++++ internal/common/parallel_client.go | 272 ++++++++++++++++++ internal/common/parallel_client_test.go | 145 ++++++++++
