FiloDB: Real-time, In-Memory Time Series...

Time series and event data is becoming huge for every business, and ingesting millions of series reliably while answering many concurrent queries from users is a huge challenge. In this talk I share the story of developing and productionizing FiloDB, an open source, in-memory time series solution built with the Scala, Akka, Kafka, Cassandra, Mesos (SMACK) stack. FiloDB is able to reliably ingest monitoring/time series data and answer tons of low latency queries at massive scale. * Why we developed our own solution after looking at Prometheus, OpenTSDB, Cassandra, etc. * Time series data model and low-latency distributed querying at scale * The benefits and challenges of off-heap, in-memory data processing at scale * Building a database for modern container environments * Challenges with scaling the Prometheus data model while remaining compatible * Persistent, recoverable data at scale with Kafka and Cassandra * Key lessons in building massively scalable, real-time, low-latency data systems
