An object placement advisor for DB2 using solid state storage

Mustafa Canim, George A. Mihaila, Bishwaranjan Bhattacharjee, Kenneth A. Ross, Christian A. Lang
2009 Proceedings of the VLDB Endowment  
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.  ...

Making updates disk-I/O friendly using SSDs

Mohammad Sadoghi, Kenneth A. Ross, Mustafa Canim, Bishwaranjan Bhattacharjee
2013 Proceedings of the VLDB Endowment  
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.  ...

Hybrid storage management for database systems

Xin Liu, Kenneth Salem
2013 Proceedings of the VLDB Endowment  
The use of flash-based solid state drives (SSDs) in storage systems is growing.  ...  We are interested in the use of hybrid storage systems, consisting of SSDs and hard disk drives (HDDs), for database management.  ...  They design an algorithm to place read-intensive pages on the SSD and write-intensive pages on the HDD. Canim, et al. [1] introduce an object placement advisor for DB2.  ...

Online Tuning of Aggregation Tables for OLAP

Katja Hose, Daniel Klan, Kai-Uwe Sattler
2009 Proceedings / International Conference on Data Engineering  
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.  ...

Turbocharging DBMS buffer pool using SSDs

Jaeyoung Do, Donghui Zhang, Jignesh M. Patel, David J. DeWitt, Jeffrey F. Naughton, Alan Halverson
2011 Proceedings of the 2011 international conference on Management of data - SIGMOD '11  
Flash solid-state drives (SSDs) are changing the I/O landscape, which has largely been dominated by traditional hard disk drives (HDDs) for the last 50 years.  ...  In this paper we propose and systematically explore designs for using an SSD to improve the performance of a DBMS buffer manager.  ...  [6] describes an object placement advisor that collects I/O statistics for a workload and uses a greedy algorithm and dynamic programming to calculate the optimal set of tables or indexes to migrate  ...

Towards Polyglot Data Stores – Overview and Open Research Questions [article]

Daniel Glake, Felix Kiehn, Mareike Schmidt, Fabian Panse, Norbert Ritter
2022 arXiv   pre-print
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.  ...
