[DB Seminar] Fall 2019 DB Group: Ankur Goyal

In this talk, we will discuss the challenges of supporting traditional database operations (ingestion, schema design, querying) to the domain of visual data, i.e. images, videos, PDFs, etc. Recent innovations in artificial intelligence have enabled computers to "see" the same structure in visual data as humans. As a result, new systems are emerging which enable users and applications to manage and query this information, as databases have successfully done for more traditional structured data.   We will start by motivating Read More

[DB Seminar] Summer 2019 DB Group: Andy Pavlo

The current research trend is on developing "learned" components to supplement and replace legacy components in database management systems (DBMSs). Such learned components use machine learning (ML) methods to identify non-trivial trends and correlations in the DBMS's runtime behavior. They then use this information to create execution strategies and data structures that are tailored to the application's access patterns. The hope is that learned components will enable new optimizations that are not possible today because the complexity of managing DBMSs Read More

[DB Seminar] Summer 2019 DB Group: Chenyao Lou

Title: NEVER use mmap for your database Abstract: MMAP can be used as the buffer pool manager for DBMSs. But is it good to use mmap for DBMSs? Chenyao is going to share evaluations for mmap, pitfalls in mmap, and methods to make mmap safe in existing DBMSs. Read More

[DB Seminar] Summer 2019 DB Group: Yangjun Sheng

Yangjun will give a practice talk for the SIGMOD/AiDM workshop.   Title: Scheduling OLTP Transactions via Learned Abort Prediction   Abstract: Current main memory database system architectures are still challenged by high contention workloads and this challenge will continue to grow as the number of cores in processors continues to increase. These systems schedule transactions randomly across cores to maximize concurrency and to produce a uniform load across cores. Scheduling never considers potential conflicts. Performance could be improved if scheduling balanced between Read More

[DB Seminar] Summer 2019: Lucas Lersch (TU Dresden)

Non-volatile memory technologies (NVM) enable persistent media to be directly accessed by the CPU through its caches. The biggest challenge introduced by NVM is the little control the application has when persisting data. This stems from the fact that it is not possible to prevent data from being evicted from the CPU cache to NVM at arbitrary points in time, possibly leading to corruption. To deal with this problem, work so far treat NVM either like storage (by always writing Read More
