May 2025 — Graph Node: Implemented IPFS Request Retry Configurability to boost reliability and deployment flexibility. Introduced GRAPH_IPFS_MAX_ATTEMPTS to configure maximum retry attempts for IPFS requests, defaulting to 100,000, replacing the previous hard-coded DEFAULT_MAX_ATTEMPTS with an environment variable (commit e50cbda7b7b2736e428db31ec93b03e14b6091a9, 'node: changed DEFAULT_MAX_ATTEMPTS to env var' #5998). Impact: reduces IPFS-related failures, enables per-deployment tuning, and improves resilience in diverse network conditions.

December 2024 performance summary for graphprotocol/indexer-rs. Delivered a configurable Receipt Processing Timeout to enhance reliability and stability of the receipt processing pipeline. Introduced a new sender_timeout_secs parameter and integrated it into the sender account and manager logic, with dynamic application when obtaining pending sender allocation IDs. This change reduces timeouts under load and improves end-to-end throughput by enabling safer scaling through tunable timeouts.
