Abstract

Espresso is a document-oriented distributed data serving platform that has been built to address LinkedIn's requirements for a  scalable, performant, source-of-truth primary store. It provides a hierarchical document model, transactional support for modications to related documents, real-time secondary indexing, on-the-fly schema evolution and provides a timeline consistent change capture stream.

Espresso has been serving as LinkedIn's online, distributed, fault-tolerant NoSQL database which currently powers approximately 30 LinkedIn applications including Member Profile, InMail (LinkedIn's member-to-member messaging system), portions of the Homepage and mobile applications, etc. Espresso has a large production footprint at LinkedIn with over a dozen clusters in use. It hosts some of the most heavily accessed and valuable datasets at LinkedIn serving millions of records per second at peak. It is the source of truth for hundreds of terabytes (not counting replicas) of data.

In this talk, our speaker will share the motivation and design principles involved in  building  Espresso,  the data model and capabilities exposed to clients, details of the replication and secondary indexing implementation, etc.
