Serialize API calls in get-result-summary.js - #170
Merged
Conversation
…erload Replace Promise.all parallel requests with sequential await calls to avoid ETIMEDOUT errors when OpenSearch's connection pool is exhausted. - Iteration-level data (params, period names, samples, primary metric) fetched sequentially instead of 4 parallel requests - Sample-level data (statuses, period IDs) fetched sequentially instead of 2 parallel requests - Metric data fetched one at a time instead of batches of 10 parallel Each request goes through the resolveRun middleware which queries OpenSearch multiple times for instance discovery, so parallel requests multiply the load significantly.
