<p><strong>Title</strong>:
The New Memory Wall and how it changes database system design
</p>

<p><strong>Abstract</strong>:
To bridge the ever-growing memory-processor speed gap (aka the "memory wall"), computer architects introduce new levels of caching that trade capacity for speed, and database designers develop cache-aware query processing algorithms since the late 1990s. Nowadays distributed query processing on the cloud is the norm; memory resources grow increasingly heterogeneous and disaggregated, mitigating the benefit of cache-aware query processing techniques. Recently, in contrast with traditional CPU-centric architectures, "memory-centric" systems that use memory pooling attract interest but also raise significant challenges as data move in unpredictable ways along a multi-dimensional memory hierarchy. Therefore, data movement emerges as a key performance bottleneck as it incurs a major cost in distributed query processing. In this talk, I will discuss the new memory wall and the challenges and opportunities it brings to database system design.
