Lightning Talk: A Fast, Concurrent Data Loader for Time-Series Data

by Glenn Philen

Summary of the talk:

In this talk, I briefly share the design of a high performance data loader used to iterating over time series data stored on disk across many individual files. The data loader aggregates data streams from different sources and of different kinds of data, orders it by timestamp, and feeds it to an offline test harness concurrently and without locking.
