SystemsLab 152.0.0

Added

• A buffer_pool_bytes config option (default 2 GB) sizes the shared decoded-block cache that backs the Parquet metric readers, letting operators trade memory for faster repeated queries against hot artifacts.

Changed

• Metric queries now stream data directly from Parquet artifacts through a bounded, shared decoded-block cache instead of loading each artifact fully into memory. This significantly reduces and caps server memory use when serving metric queries, especially for large artifacts.
