But even though OLTP workloads are dominated by point queries, they benefit from a column-major layout due to better buffer pool utilization and compression; column-majority can cause on-disk OLTP workloads to become in-memory (in- memory) OLTP workload

Abstract

A method includes logically organizing, by an object hierarchy processor, data objects in a first hierarchy. A portion of said data objects in said first hierarchy logically comprise groupings of other data objects. The object hierarchy processor physically organizes the data objects across two or more types of memory in a second hierarchy. Another part of said data objects in said second hierarchy physically comprises groupings of other data objects. Groupings of the data objects in the second hierarchy are dynamically moved across the two or more types of memory. Tracking the access level of the data objects using a data structure that maps groupings of the data objects in the first hierarchy to metadata information included in each of the data objects The combined access frequency of the data objects in the group and the current number of visitors to the data objects.

Description

technical field [0001] Embodiments of the invention relate to efficient insert and point query operations in column stores, in particular, dynamically moving tiers across two or more storage types based on the level of access to track subsets of data objects ( hierarchical) data object. Background technique [0002] There is an increasing trend of performing business intelligence (BI) queries on real-time data in databases or tabled data. Traditionally, there has been a strict separation between BI systems and online transaction processing (OLTP) systems. There is increasing market pressure for operational business intelligence, as well as for business and analytics to be performed on the same database. For BI, the trend is to lay out data in a column-major layout. This provides better query performance, better buffer pool utilization and some better compression. Traditionally, OLTP data is arranged in a row-major layout. But even though OLTP workloads are dominated by ...
