Abstract
Aggregate views of large complex data are at the core of many data analytics systems. Group-By OLAP (on-line analytical processing) queries are among the most popular but also very time consuming and particularly challenging in real-time data analytics environments. In contrast to queries for transaction processing systems that typically access only a small portion of a database, OLAP queries may need to aggregate large portions of a database which often leads to performance issues. We present new multicore and cloud based real-time OLAP systems utilizing a novel distributed index structure for OLAP, termed distributed PDCR tree. Our system supports multiple dimension hierarchies and efficient query processing on elaborate dimension hierarchies which are central to OLAP systems. It is particularly efficient for complex OLAP queries that need to aggregate large portions of a data warehouse.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
