NIFI-15682: Add Bulk Replay feature for provenance events

[Scrooge-McDucks]

Summary

This PR adds Bulk Replay support for provenance events.

NiFi already allows replaying individual provenance events, but recovering from a broader issue can still be slow and repetitive. When a processor is misconfigured, a downstream dependency fails, or a large set of FlowFiles is processed incorrectly, users may need to replay many related events rather than one at a time. This change introduces a bulk replay workflow so users can search for provenance events for a processor, select the events they want, and submit them as a server-side replay job.

This is also my first frontend feature in NiFi, so I would especially welcome feedback on the UI approach and overall user experience.

Motivation

Replay is an important recovery mechanism in NiFi, but the current experience is centered on single-event replay. That works well for targeted recovery, but it becomes inefficient when operators need to recover from larger operational issues affecting many FlowFiles.

This feature is intended to make that recovery workflow more practical by:

• allowing users to search and select many replayable provenance events for a processor
• executing replay as a managed server-side job instead of a one-off UI action
• giving users visibility into progress, failures, and job outcomes
• handling clustered execution more clearly, including disconnected-node scenarios

What changed

• Added a Bulk Replay action to the processor context menu
• Added a processor-scoped provenance search and selection dialog for replay
• Added server-side bulk replay job execution and tracking
• Added a Bulk Replay Status page in the global menu
• Added a job details view showing per-item replay status and failure reasons
• Added support for clearing successful jobs, finished jobs, or all jobs from the status list
• Added cluster-aware handling for disconnected nodes during replay
• Added configuration properties for bulk replay behavior and limits
• Added backend and frontend test coverage for the new functionality
• Added user and administration documentation for the feature

User experience

Users can right-click a processor and select Bulk Replay to open a replay search dialog scoped to that processor. From there they can:

• search provenance events for the processor
• filter results by date range and other fields
• select one or more events to replay
• optionally provide a job name
• submit the selection as a bulk replay job

Submitted jobs are visible from the Bulk Replay Status page, where users can:

• see job-level status and counts
• open a details view for a specific job
• monitor replay progress
• inspect failures and error messages
• cancel active jobs
• clear old jobs from the list

Permissions

Bulk Replay is permission-bound by provenance access. A user must have permission to query and view provenance events for the target component before they can discover eligible events and submit them for replay. This keeps bulk replay aligned with NiFi’s existing provenance security model.

Cluster behavior

Bulk replay jobs execute on the primary node.

If a replay item depends on content located on a disconnected node, the worker waits up to the configured timeout for that node to reconnect before marking the item as failed. This gives the cluster a chance to recover before replay is abandoned for affected items.

If the primary node is lost during execution, the job can be resumed by the newly elected primary node.

Configuration

This PR adds configuration for bulk replay limits and behavior, including:

• maximum concurrent bulk replay jobs
• maximum retained jobs
• disconnected-node wait timeout

Design notes

This implementation keeps the replay workflow close to the processor and provenance experience users already know, while moving execution into a managed server-side job model. That provides better visibility, better operational control, and a more scalable workflow for replaying many events.

Bulk Replay jobs are currently stored in memory. This keeps the initial implementation simpler, but it also means job state and job history are lost after a full restart. A future enhancement could add a persistent job store so replay jobs and history survive restart and provide stronger operational durability.

Testing

Testing performed includes:

• backend unit tests for execution, resource handling, job lifecycle, and configuration
• frontend test coverage for status, dialog, reducer, and interaction flows
• validation of the end-to-end replay flow from processor context menu through job submission
• validation of status updates, details view, cancellation, and clear-job behavior
• validation of disconnected-node handling and timeout-driven failure behavior

Feedback welcome

This is my first frontend feature in NiFi, so I would particularly welcome feedback on the UI flow, terminology, and any areas where the user experience could be improved.
