The Pulsar Packages Management Service can be configured to store packages on the local filesystem of the broker by using the filesystem storage provider. Package names consist of a type, tenant, namespace, name and version. Authorization of package operation…
When a configured proxy role sends a request to the broker on behalf of another user (the original principal), the broker is designed to authorize both the proxy role and the original principal and to allow the request only if both are authorized, so that the…
Apache Pulsar namespaces can restrict which roles may use a subscription, either with the Prefix subscription authentication mode, which requires a subscription name to start with the role name, or by granting permission on a subscription to specific roles. T…
Apache Pulsar shadow topics (PIP-180) are topics that read the stored messages of a source topic from that topic's managed ledger. The source topic is selected by setting the reserved topic property PULSAR.SHADOW_SOURCE. The admin REST API accepts this proper…
The Pulsar Functions worker REST API provides two endpoints that return the catalog of Pulsar IO connectors installed on the functions worker: the worker connectors endpoint (/admin/v2/worker/connectors) and the deprecated functions connectors endpoint (/admi…
The Pulsar Functions Worker provides a REST API endpoint for triggering a function, which publishes a caller-supplied value to one of the function's configured input topics. The Functions Worker performs this publish with its own broker client, which authenti…
The Apache Pulsar broker admin REST API provides a truncate operation for persistent topics (DELETE /admin/v2/persistent/{tenant}/{namespace}/{topic}/truncate). Truncating a topic moves all subscription cursors of the topic to the end of the topic and deletes…
Apache Pulsar allows an administrator to require end-to-end message encryption for all topics in a namespace by setting the encryption_required namespace policy. When this policy is set, the broker rejects messages that are published without encryption. When…
The Apache Pulsar broker admin REST API provides endpoints to read, set and remove the topic-level entry filter policy of a topic. For persistent topics these endpoints check that the caller is authorized for the entry filters topic policy operation. The corr…
The Apache Pulsar broker exposes a transaction administration REST API under /admin/v3/transactions. When authentication and authorization are enabled, most of the read endpoints of this API verify only that the request is authenticated and that the broker se…
When package management is enabled, Pulsar Functions, Sources and Sinks can be registered or updated from a package stored in the Pulsar Packages Management Service by supplying a package URL. The Pulsar Functions worker authorized these requests only against…
The Apache Pulsar WebSocket service allows a WebSocket consumer to configure a dead letter policy through query parameters of the consumer endpoint, including the deadLetterTopic parameter that names the topic to which messages are written after the maximum n…
The Pulsar broker serves two schema commands on its binary protocol: GetSchema, which returns the schema registered for a topic, and GetOrCreateSchema, which registers a new schema version for an existing topic. The broker handled both commands after checking…
Apache Pulsar's MultiRolesTokenAuthorizationProvider authorizes a client with all roles listed in a claim of its JSON Web Token (JWT). The provider is intended for use with token authentication, which verifies the token before authorization. The provider did …
