Cask

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.

Cask publishes 12 APIs on the APIs.io network. Tagged areas include Company, Big Data, Data Analytics, Data Pipelines, and Data Integration.

Cask’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, authentication, changelog, and 16 more developer resources.

APIs 12

Individual APIs this provider publishes, each with its own machine-readable definition.

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.
