Aias00 opened a new issue, #6801:
URL: https://github.com/apache/shenyu/issues/6801
- severity: Medium
- files:
`shenyu-plugin-ai/shenyu-plugin-ai-token-limiter/.../AiTokenLimiterPlugin.java:268`
(inside `appendResponse`'s `doOnNext`, per data buffer chunk of a streaming
response)
- description: `String.split("\\r?\\n")` runs `Pattern.compile` per chunk;
SSE streams emit many chunks per response. (Sibling `COMPLETION_TOKENS_PATTERN`
at `:79` and `MAPPER` at `:196` are correctly precompiled.)
- impact: Per-chunk regex compilation on streaming AI responses.
- suggested_fix: Precompile `private static final Pattern SSE_LINE =
Pattern.compile("\\r?\\n");`.
- confidence: High
