    Accelerating Large Table Scan using Processing-In-Memory Technology
    (BTW 2023, 2023) Baumstark, Alexander; Jibril, Muhammad Attahir; Sattler, Kai-Uwe
    Today’s systems are capable of storing large amounts of data in main memory. In-memoryDBMSs can benefit particularly from this development. However, the processing of the data fromthe main memory necessarily has to run via the CPU. This creates a bottleneck, which affects thepossible performance of the DBMS. The Processing-In-Memory (PIM) technology is a paradigm toovercome this problem, which was not available in commercial systems for a long time. However, withthe availability of UPMEM, a commercial system is finally available that provides PIM technologyin hardware. In this work, the main focus was on the optimization of the table scan, a fundamental,and memory-bound operation. Here a possible approach is shown, which can be used to optimizethis operation by using PIM. This method was then tested for parallelism and execution time inbenchmarks with different table sizes and compared to the usual table scan. The result is a table scanthat outperforms the scan on the usual CPU significantly.

    GTPC: Towards a Hybrid OLTP-OLAP Graph Benchmark
    (BTW 2023, 2023) Jibril, Muhammad Attahir; Baumstark, Alexander; Sattler, Kai-Uwe
    Graph databases are gaining increasing relevance not only for pure analytics but alsofor full transactional support. Business requirements are evolving to demand analytical insights onfresh transactional data, thereby triggering the emergence of graph systems for hybrid transactional-analytical graph processing (HTAP). In this paper, we present our ongoing work on GTPC, a hybridgraph benchmark targeting such systems, based on the TPC-C and TPC-H benchmarks.
