Trill fulfills a combination of three requirements for a query processor to serve the diverse big data analytics space: (1) Query Model: Trill is based on a tempo-relational model that enables it to handle streaming and relational queries with early results, across the latency spectrum from real-time to offline; (2) Fabric and Language Integration: Trill is architected as a high-level language library that supports rich data-types and user libraries, and integrates well with existing distribution fabrics and applications; and (3) Performance: Trill\u2019s throughput is high across the latency spectrum. For streaming data, Trill\u2019s throughput is 2-4 orders of magnitude higher than today\u2019s comparable streaming engines. For offline relational queries, Trill\u2019s throughput is comparable to a major modern commercial columnar DBMS.<\/p>\n<p>Trill uses a streaming batched-columnar data representation with a new dynamic compilation-based system architecture that addresses all these requirements. In this technical report, we describe Trill\u2019s new design and architecture, and report experimental results that demonstrate Trill\u2019s high performance across diverse analytics scenarios. We also describe how Trill\u2019s ability to support diverse analytics has resulted in its adoption across many usage scenarios at Microsoft.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This technical report introduces Trill \u2013 a new query processor for analytics.
