These are personal thoughts across a wide range of topics, I’m not speaking for my current or past employers in this post. As well as the video, there’s a long podcast where I discuss them with Mik Kersten.

I knew epoll() performance isn’t guaranteed, so I suspected something was affecting epoll() in a systematic way. aka “Lollipop”.

Heterogeneous and Composable Memory (HCM) offers a feasible solution for terabyte- or petabyte-scale systems, addressing the performance and efficiency demands of emerging big-data applications. CXL-based disaggregated memory provides a new opportunity with two orders of magnitude better performance than RDMA (as illustrated in Figure 2).

Last week we saw the benefits of rethinking memory and pointer models at the hardware level when it came to object storage and compression ( Zippads ). The protections are hardware implemented and cannot be forged in software. That ‘reasonable’ performance cost is a 6.8% ASPLOS’19. We answer this question affirmatively.

Not everybody agreed that the "N-ary Storage Model" (NSM) was the best approach for all workloads but it stayed dominant until hardware constraints, especially on caches, forced the community to revisit some of the alternatives. Many of the modern high-performance data warehouses such as Amazon Redshift are based on column stores.

One of the big topics at the OpenStack conference was how to prepare and implement a successful transition to 5G. With the 5G revolution, operators will need to manage hundreds of edge deployments, and maintain the physical space and hardware to achieve 1ms of latency. Here at VoltDB, we’re excited to see what else 5G will bring.
