- The idea behind NIFI-3356 was to improve the efficiency and throughput of the Provenance Repository, as it is often the bottleneck. While testing the newly designed repository,
a handful of other, fairly minor, changes were made to improve efficiency as well, as these came to light when testing the new repository:
- Use a BufferedOutputStream within StandardProcessSession (via a ClaimCache abstraction) in order to avoid continually writing to FileOutputStream when writing many small FlowFiles
- Updated threading model of MinimalLockingWriteAheadLog - now performs serialization outside of lock and writes to a 'synchronized' OutputStream
- Change minimum scheduling period for components from 30 microseconds to 1 nanosecond. ScheduledExecutor is very inconsistent with timing of task scheduling. With the bored.yield.duration
now present, this value doesn't need to be set to 30 microseconds. This was originally done to avoid processors that had no work from dominating the CPU. However, now that we will yield
when processors have no work, this results in slowing down processors that are able to perform work.
- Allow nifi.properties to specify multiple directories for FlowFile Repository
- If backpressure is engaged while running a batch of sessions, then stop batch processing earlier. This helps FlowFiles to move through the system much more smoothly instead of the
herky-jerky queuing that we previously saw at very high rates of FlowFiles.
- Added NiFi PID to log message when starting nifi. This was simply an update to the log message that provides helpful information.
NIFI-3356: Fixed bug in ContentClaimWriteCache that resulted in data corruption and fixed bug in RepositoryConfiguration that threw exception if cache warm duration was set to empty string
NIFI-3356: Fixed NPE
NIFI-3356: Added debug-level performance monitoring
NIFI-3356: Updates to unit tests that failed after rebasing against master
NIFI-3356: Incorporated PR review feedback
NIFI-3356: Fixed bug where we would delete index directories that are still in use; also added additional debug logging and a simple util class that can be used to textualize provenance event files - useful in debugging
This closes#1493
* Corrected handling of corrupt journal file records that prevents instance startup and loss of records from corrupt files. Specifically, exception handling was expanded to cover failures on records after the first the same as failures on the first record.
* Adjusted log messages to reflect that the remainder or all of the journal will be skipped, not just the current record.
This closes#1485.
* Remove function based on JDK source.
* Add new function to find bytes based on RFC3629.
* Add field name to log entry when field is truncated.

This closes#1475
* Updated StandardRecordWriter, even though it is now deprecated to consider the encoding behavior of java.io.DataOutputStream.writeUTF() and truncate string values such that the UTF representation will not be longer than that DataOutputStream's 64K UTF format limit.
* Updated the new SchemaRecordWriter class to similarly truncate long Strings that will be written as UTF.
* Add tests to confirm handling of large UTF strings and various edge conditions of UTF string handling.

- Fixed check verifying source/destination when creating a connection.
NIFI-3133:
- Only showing the go to link when the source component is not a remote port.
NIFI-3133:
- Removing unnecessary checking of remote group port authorization since it's handled by the parent RPG.
NIFI-3133:

This closes#1202
This closes#840
Removed partial file check (based on missing first file)
Added condition to merge if at least one journal files available on disk. If all files are missing from disk that is considered an error.
Added retry logic to prevent endless thread execution when encountering errors (such as missing files).
- Introducing data resource for authorizing provenance events and queue listing.
- Authorizing entire proxy chain for data resource and data transfer resource.
NIFI-2338:
- Ensuring that replay authorization only happens once.
- Allowing users with access to policies for a component to be able to access all policies for that component.
-- Includes the component, data, data transfers, and policies.
- Fixing drop request completion to update the correct queued field.
- Fixing access control check for listing and emptying queues.
- Reseting selected policy when re-opening the policy management page.
- Fixing button/link visibility for available actions in policy management page.
- Fixing policy issues with policy removal when the underlying component is deleted.
- Updating file authorizer seeding to grant data access to node's in the cluster.
This closes#720.

- Passing client address along in user context on authorization requests
- This closes#628
- Updating UI according to permissions through out the application.
- Shuffling provenance events, template, and cluster search REST APIs according to resources being authorized.
- Moving template upload controls.
- Removing username where appropriate.
- Addressing issues when authorizing flow configuration actions.
- Code clean up.
