Snowflake’s journey from Batch to Streaming Abstract: In this talk we will see how Snowflake evolved from a classic batch processor, where the whole input dataset is stored on disk waiting to be processed, to a stream processor where data can be processed as it comes. In addition, we will see how it did this without breaking the “single-product” principle where everything is exposed as classic Tables and users do not need to learn a new paradigm to leverage its new capabilities. https://dasya.itu.dk/posts/talkbyvasilikikalavri/ Mon, 02 Sep 2024 00:00:00 +0000 https://dasya.itu.dk/posts/talkbyvasilikikalavri/ Vasiliki Kalavri will visit the DASYA research group and give a talk in the Advanced Data Systems class on September 12. Cryptographically secure analytics in the Cloud Abstract: Enabling secure outsourced analytics with practical performance has been a long-standing research challenge in the data management and systems communities. In this talk, I will present recent work that allows multiple data holders to contribute their data towards a joint analysis in the cloud, while keeping the data siloed even from the cloud providers. https://dasya.itu.dk/posts/damon23/ Mon, 19 Jun 2023 00:00:00 +0000 https://dasya.itu.dk/posts/damon23/ Paper presented at DaMoN 2023 DaMoN Niclas presented our paper surveying the eBPF ecosystem and introducing Delilah, the first publicly described computational storage device supporting eBPF-based code offload. The paper was presented at the DaMoN Workshop, held in conjunction with SIGMOD/PODS 2023 in Seattle, US. Abstract The idea of pushing computation to storage devices has been explored for decades, without widespread adoption so far. The definition of Computational Programs namespaces in NVMe (TP 4091) might be a breakthrough. https://dasya.itu.dk/posts/adms20sebs/ Mon, 31 Aug 2020 00:00:00 +0000 https://dasya.itu.dk/posts/adms20sebs/ Another paper presented at ADMS 2020 ADMS Sebastian Baunsgaard and Sebastian Benjamin Wrede, DASYA alumnis, presented our paper, Training for Speech Recognition on Coprocessors, at ADMS 2020. https://dasya.itu.dk/posts/adms20/ Mon, 31 Aug 2020 00:00:00 +0000 https://dasya.itu.dk/posts/adms20/ Paper presented at ADMS 2020 ADMS Niclas presented our paper on the practical security of hash-based authentication with modern hardware architecture. The paper concludes that passwords only adhering to the minimum requirements of major websites are easily crackable with home hardware. The paper was presented at ADMS 2020, which was the 11th edition of the workshop. It was held online for the first time due to the COVID-19 pandemic. https://dasya.itu.dk/posts/zsolt/ Thu, 07 May 2020 00:00:00 +0000 https://dasya.itu.dk/posts/zsolt/ Re-imagined Architectures: Towards more Efficient Data-Intensive Systems Abstract Today’s datacenters host data processing and data management systems that routinely span hundreds of computers. At such scale, data movement and coordination is becoming a bottleneck at various levels, limiting further scalability. One way of reducing data movement bottlenecks is by pushing parts of the computation closer to the data source and, thanks to the changing hardware landscape, this can be done using emerging specialized hardware in an efficient manner. https://dasya.itu.dk/posts/ecir20/ Wed, 15 Apr 2020 00:00:00 +0000 https://dasya.itu.dk/posts/ecir20/ Paper presented at ECIR 2020 ECIR Omar presented our paper on Exquisitor as the new state of the art interactive learning approach for large-scale multimedia collections. The paper was presented at ECIR 2020, which was the 42nd edition of the conference. It was held online for the first time due to the COVID-19 pandemic. You can watch the talk on YouTube here. Abstract Interactive learning has been suggested as a key method for addressing analytic multimedia tasks arising in several domains. https://dasya.itu.dk/posts/cidr20/ Mon, 13 Jan 2020 00:00:00 +0000 https://dasya.itu.dk/posts/cidr20/ Paper presented at CIDR 2020 CIDR Philippe presented our paper looking back at Open-Channel SSDs, their impact on the storage industry and the lessons we learned in the OX project. The paper was presented at the CIDR Conference, held for the first time in Amsterdam. Abstract Open-Channel SSDs are storage devices that let hosts takefull control over data placement and I/O scheduling. In recent years, they have gained acceptance in data centers (e. https://dasya.itu.dk/posts/hpts20/ Fri, 01 Nov 2019 00:00:00 +0000 https://dasya.itu.dk/posts/hpts20/ Three talks at Bay Area Pınar gave three talks during her visit to Bay Area. First stop was Facebook headquarters at Palo Alto, where she visited RocksDB teams and gave a talk on “LSM Management on Computational Storage”. Then, at the HPTS workshop, she gave a gong-show talk on “Training for Speech Recognition on Co-processors”, which was voted the best gong-show talk by the audience, and a regular talk on “Data-Intensive Systems in the Microsecond Era”.
