      Epic Summary

      Summary

      Block Processing Spike has started proving key design concepts about the new block-at-a-time model, including its compatibility with MQL semantics. In this project, one mature block processing component, ie the container stages, would be designed, implemented and integrated with Time Series Bucket Collection access paths, ie collection and index scans.

      Motivation

      Ultimate goal is to improve analytical query performance by investing in more efficient query execution models. This new model will first be applied to Time Series queries. This project will start developing proven concept and integrating with the first usecase - Time Series queries. These queries can then benefit from both the strength of the improved SBE as well as the block processing model.
