- 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
The 'exec' command added by NIFI-2689 affected restart behavior
negatively as 'exec' command will not execute subsequent commands in the
shell script.
This commit changes 'exec' is added only when 'run' is specified.
This closes#1523.

Before this fix, files with the latest timestamp within a listing
iteration are always be held back one cycle no matter how old it is.

- Add 'nifi.flow.configuration.archive.max.count' in nifi.properties
- Change default archive limit so that it uses archive max time(30 days)
and storage (500MB) if no limitation is specified
- Simplified logic to delete old archives
This closes#1460.

- Added Signal Counter Delta property
- Added Signal Buffer Count property
- Added processor property name and display name
- Changed IOException handling from routing it to failure to throw
RuntimeException, so that NiFi framework can yield the processor for a while and try again

This closes#1466.
- Added detailed description about how the URL property works with
GetHTMLElement
- Added Expression support with URL
- Made URL property dynamic with ModifyHTMLElement and PutHTMLElement,
since it won't be used to alter HTML element and need not to be
specified. Making it a dynamic property let existing processor configuration stays valid
