[SYSTEMDS-2719] Lineage exploitation in the buffer pool (datagen ops) For matrices that are results of data generation instructions such as RAND, we store their lineage alongside the data. Under memory pressure, these matrices do not go to the buffer pool. We recompute them from lineage instead of reading evicted buffers from FS. This potentially results in fewer evictions and IO. AMLS project SS2020. Closes #1096.
Overview: SystemDS is a versatile system for the end-to-end data science lifecycle from data integration, cleaning, and feature engineering, over efficient, local and distributed ML model training, to deployment and serving. To this end, we aim to provide a stack of declarative languages with R-like syntax for (1) the different tasks of the data-science lifecycle, and (2) users with different expertise. These high-level scripts are compiled into hybrid execution plans of local, in-memory CPU and GPU operations, as well as distributed operations on Apache Spark. In contrast to existing systems - that either provide homogeneous tensors or 2D Datasets - and in order to serve the entire data science lifecycle, the underlying data model are DataTensors, i.e., tensors (multi-dimensional arrays) whose first dimension may have a heterogeneous and nested schema.
