feat(compaction): add adaptive batch sizing on failure#141
Merged
Conversation
When compaction fails with recoverable errors (segfault, OOM kill, memory allocation errors), the batch is automatically split in half and retried recursively. This continues until either success or minimum batch size (2 files) is reached. - Add ClassifySubprocessError() to categorize subprocess failures - Add compactFilesAdaptively() for recursive batch splitting - Classify errors as recoverable (segfault, OOM, memory) or permanent (permission denied, file not found) - Non-recoverable errors are not retried to avoid wasting time - Maximum split depth of 4 levels (e.g., 30 → 15 → 7 → 3 files) - Includes comprehensive unit tests for error classification
