Events - processing of eventseventarchitectureconfigurationprocessor

Every module can publish their own event types. Basic (core) event types

• CREATE - synchronous, new entity is created
• UPDATE - synchronous, entity is updated
• DELETE - synchronous, entity is removed
• NOTIFY - asynchronous, notify about entity is changed (CU).
• EAV_SAVE - synchronous, some entity extended attribute is modified (CUD) - it is synonym for NOTIFY type ⇒ notify about entity extended attribute is changed (only extended attribute is changed). When entity is saved together with extended attributes, then only source event (e.g. CREATE) on owner entity is published (⇒ eav attributes are saved after owner entity is saved in once process line - e.g. CREATE).

Different (and custom) event types can be used for different entities.

Event is published with content and specific event type (e.g. CREATE, PASSWORD). Processors can be registered by content type and event type - e.g. process event with IdmIdentityDto content and event type CREATE ⇒ other event contents and other event types will not be processed by this processor.

Supported events for individual entities:

• core:
  • IdmAuthorizationPolicyDto - authoriyation policies
    • supports base event types CREATE, UPDATE, DELETE

• vs:
  • VsRequestDto - Request for account change in virtual system

• rpt:
  • RptReportDto - generate report

A page has been created directly in the application on the module page for an overview of all entity types and event types migrating through event processing. All the registered processors including the configuration are listed there:

CzechIdM 8.0.0 ushered in a new feature - asynchronous event processing. New event type NOTIFY was added, all previous events (CREATE, UPDATE, DELETE, EAV_SAVE etc.) are still synchronous.

Before event is persisted into queue, then event priority is evaluated, priority types:

• IMMEDIATE - immediate ~ synchronously. Event will be executed synchronously.
• HIGH - asynchronously (7 / 10 in one cycle)
• NORMAL - asynchronously (3 / 10 in one cycle)

Priority can be set to event manually or registered processors can vote about event's priority - see AsyncEntityEventProcessor - the highest priority is used.

Execute date can be set to event manually. Event with priority HIGH or NORMAL will be processed after given date. Can be used for events, which could be executed sometimes "in night".

When internal scheduled task for executing event from queue is processed, then duplicate events are removed.

Duplicate event is event with the same:

• owner
• event type
• event properties
• original source (embedded dtos and audit fields are ignored).

Older duplicate events are removed - the newest event is used. Events are processed by priority in bulk, default bulk size is 100 events ⇒ duplicates are removed only in this bulk (not configurable for now, see future development). Bulk size is designed this way, because events are processed by priority - event with HIGH priority should not wait too long for another bulk is begin to process. Remove duplicates should be redesigned from scratch - remove duplicates through whole queue.

Notification about registered asynchronous processors is prepared, when an asynchronous event is published. Notification is send into topic core:event - uses console log by default and is send to currently logged identity - e.g. identity is saved, but provisioning will be executed asynchronously. Localization for asynchronous processors was added on frontend (see key acc:processor.identity-save-processor).

• Scheduler - configure internal scheduled tasks for processing events from queue.
• Event processing - configure asynchronous event processing
• Processors - configure entity event processors.

• 0 - basic / core functionality - operation save, delete etc.
• 50 - save eav, which are send together with owner's dto
• 100 - automatic roles computation.
• 1000 - after save - e.g. sends notifications.
• 10000 - publish NOTIFY event about entity is changed.
• -1000 - before delete provisioning (before identity role is deleted).
• Identity:
  • -2000 - validate password in acc module - checks all system password policies and idm default policy ⇒ all policies are evaluated in one request. If acc module is enabled, then core password validation processor can be disabled.
  • -1000 - validate password in core module - checks idm default policy.
  • 100 - persist password
• Contract:
  • 100 - Automatic roles recount while identity contract is saved, updated or deleted / disabled.
  • 200 - Contract exclusion, end and enable.
• LongRunningTask:
  • 100 - execute scheduled long running tasks, which depends on currently ended scheduled task.
• Provisioning:
  • -5000 - check disabled system
  • -1000 - compute attributes for provisioning (read attribute values from target system)
  • -500 - check readonly system
  • 0 - execute provisioning (create / update / delete)
  • 1000 - execute after provisioning actions (e.g. sends notifications)
  • 5000 - archive processed provisioning operation.

Other orders can be found directly in application, see supported event types.

Processors can be configured through Configurable interface by standard application configuration.
