[DB Seminar] Fall 2017: Barry Morris (NuoDB)
Speaker:
Barry Morris
System:
NuoDB

For decades the industry has sought solutions to the challenge of efficient distributed transactions, and ideally to elastically-scalable distributed transactions.  The opportunity for such systems is to provide on-demand capacity, redundancy-based uptime models, and automation of labor-intensive administrative tasks.  Additionally Elastic SQL systems may provide a route to geo-distributed transactions processing.  The approaches to this challenge have all involved very...

[DB Seminar] Fall 2017: Joy Arulraj
Speaker:
Joy Arulraj

For the first time in 25 years, a new non-volatile memory (NVM) category is being created that is two orders of magnitude faster than current durable storage devices. The advent of NVM fundamentally changes the dichotomy between memory and durable storage in database systems. These new NVM devices are almost as fast as DRAM, but all writes to it are... Read More

TimescaleDB: Re-engineering PostgreSQL as a Time-series Database (Michael Freedman)
Speaker:
Michael J. Freedman
System:
TimescaleDB
Video:
YouTube

Time-series data is now everywhere—IoT, user event streams, system monitoring, finance, adtech, industrial control, transportation, and logistics—and increasingly used to power core applications. It also creates a number of technical challenges: to ingest high volumes of structured data; to ask complex, performant queries for both recent and historical time intervals; to perform specialized time-centric analysis and data management. And this... Read More

Fintan Quill
System:
kdb
Video:
YouTube

Trying to solve the data riddle purely through the lens of architecture is missing a vital point: The unifying factor across all data is a dependency on time. The ability to capture and factor in time is the key to unlocking real cost efficiencies. Whether it’s streaming sensor data, financial market data, chat logs, emails, SMS or the P&L, each...

Speaker:
Shasank Chavan

Analytic workloads in data management systems are dominated by joins, aggregations, scan and filtering costs. In-Memory columnar databases have significantly optimized scans using compressed data formats and SIMD vectorization techniques, but have made little impact to the rest of the query execution plan. The Oracle Database In-Memory (DBIM) Option introduced new SQL execution operators that accelerate a wide range of... Read More
