Optimal column layout for hybrid workloads

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 … WebIn this paper, we propose MTO, an instance-optimized data layout framework that determines the blocking strategy for all tables in a multi-table database in the presence of joins, such as in a star or snowflake schema common in real-world workloads. Webdatabase under hybrid workloads. In the system, we introduce a machine learning method to build a cost model for the storage engine, and a column-oriented data layout generation algorithm. Experimental results show that the proposed system can choose the optimal combination of storage engine and data model granite falls auto body
