URL: https://github.com/apache/doris/pull/61326
- Add get_cache_size() and get_cache_line_size() methods to CpuInfo
- Add StreamingHtMinReductionEntry struct and
get_streaming_ht_min_reduction() method
- Replace static STREAMING_HT_MIN_REDUCTION config with dynamic calculation
based on L2/L3 cache size
- Update include paths in streaming_aggregation_operator.cpp and
distinct_streaming_aggregation_operator.cpp
- Change namespace from doris to doris::pipeline in
streaming_aggregation_operator.cpp
This change enables better adaptation to different hardware environments by
dynamically calculating hash table expansion thresholds based on actual CPU
cache sizes.
