Introduction to Spark
Presented by Carol McDonald, MapR Technologies
Apache Spark is a fast and general engine for large-scale data processing. In contrast to Hadoop's two-stage disk-based MapReduce paradigm, Spark's in-memory primitives provide performance up to 100 times faster for certain applications.
The Spark software stack includes a core data-proccessing engine, an interface for interactive querying, Sparkstreaming for streaming data analysis, and growing libraries for machine-learning and graph analysis. Spark is quickly establishing itself as a leading environment for doing fast, iterative in-memory and streaming analysis.
This talk will give an introduction the Spark stack, explain how Spark has lighting fast results, and how it complements Apache Hadoop.
Please RSVP!

Codetown is a social network. It's got blogs, forums, groups, personal pages and more! You might think of Codetown as a funky camper van with lots of compartments for your stuff and a great multimedia system, too! Best of all, Codetown has room for all of your friends.

At GrafanaCON 2026 in Barcelona, Grafana Labs announced Grafana 13 with the new Loki Kafka-backed architecture at the ingestion layer and the AI Observability in Grafana Cloud to monitor and evaluate AI systems in real time. In particular, the new CLI called GCX was announced, designed to surface Grafana Cloud data inside agentic development environments.

Observability must evolve with serverless, event-driven architectures. OpenTelemetry can decouple telemetry from vendors, letting developers emit consistent, high-quality data that explains real system behavior. Shared vocabularies and good telemetry make debugging faster and improve reliability, speed, and developer productivity.

Frank Yu shares Coinbase’s engineering philosophy for building resilient, fair, and fast financial exchanges. He explains the power of a single-threaded architecture combined with the Raft consensus algorithm to maintain 24/7 availability. He discusses how determinism enables zero-downtime rolling deployments and the ability to replay production logs for perfect bug reproduction.

Dropbox reduced its backend monorepo from 87GB to 20GB by optimizing Git delta compression in collaboration with GitHub. The changes improved clone times, CI performance, and developer velocity, highlighting how repository storage inefficiencies can impact large-scale engineering workflows.

The panelists share insights on evolving company culture. They discuss leveraging feedback loops, lending social capital, and the friction between legacy bureaucracy and agile engineering. The panel explains how to maintain cohesion in remote teams and use interviews to uncover the true "unmanicured" culture of a firm.
