Cask Data, Inc. was the enterprise big-data startup, backed by Andreessen Horowitz, that built and open-sourced CDAP — the Cask Data Application Platform — a framework for building and running data analytic applications and data pipelines on Hadoop, Spark, Kubernetes, and the cloud. Cask was acquired by Google Cloud; CDAP continues as an Apache-2.0 open source project under the github.com/cdapio organization and powers Google Cloud Data Fusion. CDAP's programmatic surface is its HTTP RESTful "Microservices" API — 21 documented service families (Lifecycle, Artifact, Metadata, Metrics, Logging, Namespace, Pipeline, Preferences, Profile, Provisioners, Replication, Reports, Security, Service, Workflow, Monitor, Dashboard, Configuration, Transaction Service, System Workers) served under a /v3 path prefix from a self-hosted CDAP router, with Bearer access tokens issued by the CDAP authentication server. The company's own cask.co domain and developer portal are gone; the surviving surfaces are cdap.io, the CDAP documentation wiki, the cdapio GitHub organization, and the io.cdap.cdap / co.cask.cdap artifact groups on Maven Central.

## APIs (12)

- **CDAP Microservices API** — The CDAP HTTP RESTful API, documented as "Microservices". All endpoints sit under a /v3 path prefix on a self-hosted CDAP router (default port 11015, or 10443 when SSL is enable...
- **CDAP Lifecycle Microservices** — Deploy, start, stop, and manage the lifecycle of CDAP applications and the programs they contain within a namespace.
- **CDAP Artifact Microservices** — Manage CDAP artifacts — the packaged application and plugin JARs that applications are created from — including deployment, versioning, and plugin inspection.
- **CDAP Metadata Microservices** — Search, annotate, and retrieve business and technical metadata and lineage for CDAP entities such as applications, datasets, programs, and fields.
- **CDAP Metrics Microservices** — Query the metrics CDAP collects for system and user programs, including time-series queries across metric contexts and tags.
- **CDAP Logging Microservices** — Retrieve and download logs emitted by CDAP system services and by user applications and programs, with filtering by time range and log level.
- **CDAP Namespace Microservices** — Create, list, and delete CDAP namespaces — the multi-tenancy boundary that isolates applications, datasets, and metadata. The cdap, default, and system namespaces are reserved.
- **CDAP Pipeline Microservices** — Programmatically create, deploy, run, and inspect CDAP data pipelines (the Hydrator / Data Fusion pipeline application type) and their plugin configurations.
- **CDAP Replication Microservices** — Manage CDAP replication (change data capture) jobs that stream changes from source databases into analytic targets such as BigQuery.
- **CDAP Security Microservices** — Manage CDAP secure store keys and authorization privileges, roles, and policies for principals operating against a security-enabled CDAP cluster.
- **CDAP Workflow Microservices** — Inspect and control CDAP workflows — multi-node program orchestration — including run records, node states, local datasets, and workflow tokens.
- **CDAP Preferences Microservices** — Read and write preferences — the hierarchical configuration key/value pairs resolved across the instance, namespace, application, and program scopes.
