Cincinnati Go Meetup — Pilosa



This talk will cover Pilosa - a high performance, distributed bitmap index written in Go. Bitmap indexes are widely used inside various data systems to power difficult analytical queries; while conceptually simple, research and improvements into storing and computing over bitmaps has continued unabated for decades. Pilosa leverages the latest and most successful bitmap techniques to power a distributed data indexing system that excels at a variety of analytical workloads while consuming less space and memory than many similar systems. We'll take a look at how Pilosa uses distributed bitmaps to support multi-field GROUP BY queries and very complex WHERE clauses over billions of records with sub-second query performance. Perhaps more importantly, we'll discuss how Go has enabled us to productively develop this technology and deploy it in various production systems.
