Are You Sure You Want to Use MMAP in Your Database Management System? Memory-mapped (MMAP) file I/O is an OS-provided feature that maps the contents of a file on secondary storage into a program’s address space. The program then accesses pages via pointers as if the file resided entirely in memory. The OS transparently loads pages only when the program references them and automatically evicts page

Time series and streaming databases are hot right now. That's why my second wife left me. Just like a lot of people these days, everybody wants one or thinks that they want one. Given this, we are bringing back another season of database technical talks at Carnegie Mellon University in Fall 2017. The "Time Series Database Lectures" is a semester-long seminar series featuring speakers from the lead
Strap yourself in kids, because we have an amazing line-up of technical talks coming to Carnegie Mellon University in Fall 2014. Seven Databases in Seven Weeks is a semester-long seminar series with the leading developers of NoSQL and NewSQL database management systems. Each speaker will present the implementation details of their respective systems and examples of the technical challenges that th
What’s Really New with NewSQL? Andrew Pavlo Carnegie Mellon University pavlo@cs.cmu.edu Matthew Aslett 451 Research matthew.aslett@451research.com ABSTRACT A new class of database management systems (DBMSs) called NewSQL tout their ability to scale modern on-line transac- tion processing (OLTP) workloads in a way that is not possible with legacy systems. The term NewSQL was first used by one of th
Peloton is a relational database management system that is designed for autonomous operation. The system’s integrated planning component not only optimizes the system for the current workload, but also predicts future workload trends before they occur so that the system can prepare itself accordingly. It also enables new optimizations that are not possible today because the complexity of managing
