Original Pull Request: https://github.com/langgenius/dify/pull/27549

State: closed
Merged: Yes

Summary

Closes #27547
This PR optimizes tracing config decryption performance in OpsTraceManager by implementing batch decryption and LRU caching for decrypted configurations. The changes reduce cryptographic overhead and eliminate redundant decryption operations for identical tracing configs.

Key Changes:

  • Batch Decryption: Replaced individual decrypt_token() calls with batch_decrypt_token() for improved efficiency
  • LRU Cache: Added decrypted_configs_cache to cache decrypted tracing configurations
