An object placement advisor for DB2 using solid state storage
2009
Proceedings of the VLDB Endowment
Preserved Fulltext
In this paper we propose a tool called "Object Placement Advisor" for making a wise decision for the object placement problem. ...
Considering the price and limited storage capacity of solid state disks, the database administrator needs to determine which objects (tables, indexes, materialized views, etc.), if placed on the SSD, would ...
INTRODUCTION Solid state disks (SSDs) have been introduced by a number of vendors in the last few years. SSDs provide persistent data storage using a form of solid-state flash memory. ...

To achieve this end, we re-design persistent index data structures in the storage hierarchy to employ an extra level of indirection. ...
The indirection level is stored on solid state disks that can support very fast random I/Os, so that traversing the extra level of indirection incurs a relatively small overhead. ...
To address this dilemma, we utilize a solid state storage layer. ...

In this paper we present an online approach for adjusting the configuration dynamically to the current workload. ...
This problem is known as the view selection problem: choosing the optimal set of aggregation tables (called configuration) for a given workload. ...
Some of these tools work also at the OLAP level, e.g., the IBM DB2 Cube View Optimization Advisor. Even Mondrian offers an Aggregation Designer, but this tool is not workload-aware. ...

This paper describes representative real-world use cases for data-intensive applications (OLTP and OLAP). It derives a set of requirements for polyglot data stores. ...
Since no single platform copes everything, various stores (RDBMS, NewSQL, NoSQL) for different workloads and use-cases have been developed. ...
The Storage Advisor module splits each data set into fragments and chooses the backend system for each fragment based on the underlying data model, where to store them accordingly. ...
