Core Concepts

Understanding how LyftData models control, orchestration, and execution helps you design pipelines that scale cleanly from a local experiment to production workloads. The three pillars are the Server (control plane), Jobs (pipeline definitions), and Workers (runtime execution).

The server is LyftData’s source of truth. It stores configuration, maintains system health, and orchestrates work across workers. Because the Server also fronts the web UI and API, it is the hub for both day-one configuration and day-two operations.

Responsibilities

  • Persist and version Job definitions and associated assets
  • Schedule work by matching Jobs to eligible Workers and enforcing concurrency policies
  • Aggregate metrics, logs, and alerts so operators have a single pane of glass

A Job describes how one stream of data moves from an input through optional processing steps to a single output. Jobs can be authored as YAML, managed through the visual editor, or generated through automation.

Lifecycle

  1. Define the input (files, APIs, queues, databases, and more) and the trigger that determines when it should run
  2. Add Actions—filters, parsers, enrichers, or Lua scripts—to shape the payload
  3. Select a single output destination (warehouse, lake, search index, message queue, etc.)
  4. Stage and deploy; the Server handles scheduling, retries, and observability

Composing flows

A single Job always links one input to one output. Compose multi-step or branching flows with Workflows, which make routing, transport, placement, and deployment intent explicit. A worker channel is one available transport: it is an in-process pathway between jobs placed on the same worker, not a cross-worker broker.

Job: ingest-events -> Channel: ingest-feed
Job: enrich-events <- Channel: ingest-feed -> Channel: analytics-fanout
Job: load-warehouse <- Channel: analytics-fanout
Job: push-alerts <- Channel: analytics-fanout

This worker-channel pattern can keep a same-worker pipeline modular, but it has no external durability and does not survive a worker boundary. For multi-worker delivery, replay, or independent recovery, choose a suitable durable transport. See Routing and Fan-out, Transports and Durability, and Delivery Semantics.

Workers are stateless runtimes that pull assignments from the Server, materialize Job pipelines, and emit telemetry. You can run Workers next to data sources for low-latency ingestion or in a central plane for simplified networking.

How Workers operate

  1. Register with the Server and advertise capabilities (connectors, capacity, and optional labels)
  2. Receive Job payloads and instantiate the runtime (inputs, actions, outputs, triggers)
  3. Execute the pipeline, streaming metrics, logs, and traces back to the Server
  4. Tear down gracefully and report status so operators and the control plane can diagnose the stopped workload.

Worker isolation can limit blast radius to the jobs placed there. Additional licensed workers provide placement and capacity options, but safe scale-out depends on the input’s ownership model, state, ordering, transport, and recovery semantics; merely adding a worker does not redistribute every job safely.

  • Capacity planning – Establish a baseline by tracking throughput, concurrency, and memory per Job. Add Workers when queue depth or execution latency grows faster than expected.
  • Observability – Forward logs and metrics from Workers to your monitoring stack. Familiarize yourself with the Troubleshooting guide and set alerts on retry spikes or sustained channel backlogs.
  • Resilience – Use staging and canary deployments before promoting configuration changes. Choose durable stage boundaries when replay or independent recovery is required; worker channels are worker-local and in-memory.
  • Security – Apply TLS, RBAC, and secret management practices outlined in the Install runbooks before attaching production datasets.

Most teams iterate through the Server UI during development, then promote Jobs via source control and CI. Environment variables and configuration files govern cluster-wide behavior (licensing, telemetry sinks, connector credentials). For deeper reference, explore the Configuration docs and topic-specific guides across Install, Build, and Operate sections.

By internalizing these concepts—Server authority, Job composition, Worker execution, and channel-driven orchestration—you can assemble reliable pipelines without re-implementing scheduling, scaling, or observability from scratch.
