Optimal column layout for hybrid workloads
Webof a flexible storage model for HTAP workloads in Section 2. Next, in Section 3, we describe the design of our system architecture based on this model. We then present the concurrency control mechanism that enables the DBMS to support hybrid workloads in Section 4, followed by our on-line layout reorganization technique in Section 5. WebMay 24, 2024 · OLAP engines have been repeatedly shown to perform better if data is stored in column stores. Column stores provide better support for data compression and are more optimized for in-memory processing of large volumes of data. Thus, the primary focus was on developing new storage layouts that can efficiently support both OLTP and OLAP …
