Elli,

Joe gave an excellent talk last year at OSCON 2015.

Shows a bit of the provenance features and searchability of NiFi.

Re: Auto-Organize Layout

[Elli Schwarz]

Joe, 

Responses to your bullets: 1) I wasn't aware of the details of how provenance 
works. After reading about it, it seems quite powerful and it may help for some 
cases. I especially like the ability to replay files and track timing of 
events. However, there are some problems I think I've experienced in regards to 
provenance: we have thousands of flowfiles going through daily. We like to keep 
the flowfiles from certain processors for several days, but if we keep them 
from all processors we will quickly run out of disk space. When I first 
upgraded to 0.3.0, it had provenance on by default (I think that was a bug, 
since in 0.2.0 it was off by default) and I quickly and unexpectedly ran out of 
disk space on my production server. Furthermore, there are many cases where we 
store a collection of flowfile content in a directory and we grep looking for 
certain strings to debug something - can you do something similar to a grep on 
content through provenance? Can you select which processors you want to store 
flow files for so not to fill up the disk with flowfile content from processors 
we don't care as much about? If the answer to these questions could be yes, 
then I think provenance would work for the kind of tracking I've done with 
PutFile and LogAttributes.
2) For emphasizing the main parts of a flow, I think the ability to align 
selected processors would help. I would select the main processors, line them 
up horizontally, and maybe it would automatically move other processors above 
or below. Also, maybe I didn't fully explain my processor minimization idea - I 
would like an option on a processor to "show icon only" so instead of a full 
processor box with all the stats and details, it would look something like a 
Processor Group port looks - no stats, just text and some icons indicating 
started/stopped/disabled. (It should still look differently than a port does so 
no one gets confused).
Of course, I look forward to hearing what others have to say about these ideas!

1) How best to handle log/debug sort of flows

One thing to consider is that with our provenance and content archival
it eliminated the need for many uses of
LogAttribute and for PutFile for these cases.  Something to consider.

2) How best to de-emphasize 'special case' handling of flows or parts

Re: Emphasising important processors, is there a resize feature to make
some boxes on the canvas bigger/smaller than others? Then the main flow
could be "follow the big boxes"

Or! Allow them to auto-size based on volume. That would be neat.

Re: Auto-Organize Layout

[Elli Schwarz]

Joe,
What I'm referring to as far as emphasizing "important" processors is that 
there are many places in my workflow where I do a PutFile for logging purposes, 
and I have one for success and a separate one for failure. So for many of my 
main processors, there are two connectors to PutFiles. This makes the workflow 
look very cluttered, and when doing a demo it is difficult to see the main path 
that flowfiles are taking without explanation, when I'd like it to be 
intuitive. In fact, there are some cases that I really want to add PutFiles for 
logging but since it will make the workflow look so cluttered I don't do it. 
Maybe this problem can be solved by an option to route all failures or even 
successes from some or all processors to do a PutFile to a specific folder? 
Maybe we can minimize some processor such as these PutFiles to a small icon 
instead of the whole box to save screen space? I often don't care about 
processor stats for these processors anyway, but maybe they'd be displayed on 
mouse hover.

Furthermore, in some of my workflows I have my main tasks that deal with the 
actual processing of the incoming data, and other "side tasks" that I do with 
the data like collect special metrics,  storing some metadata in a special 
database, sending status emails, etc. I handle this now with Processor Groups, 
and that helps, but I find it a bit unwieldy to create many processor groups 
that only have two or three processors in them (and then the processor group 
needs the input/output ports, further complicated an otherwise simple 
workflow). There are also cases where for some failures, I have a ControlRate 
processor and then retry the flowfile after a certain period of time - this is 
not a "main" part of the workflow, but it clutters it and it's not intuitive to 
see what's happening. I think I'd like to solve this problem by just being able 
to align selected processors that I consider more important, and having the 
others off to a side.

As far as accidentally dragging processors is concerned, sometimes I intend to 
the pan screen and end up moving a processor or moving a label that I used to 
highlight a section of my flow. For demos, it would be nice to lock the entire 
page layout. Maybe this can be accomplished with a button on the top right 
corner to enable/disable layout changes or disable adding new processors, and 
only allow viewing processor properties - a sort of "read only" mode.
Thanks for taking my feedback into consideration. I still find Nifi incredibly 
useful for handling my complicated workflows and appreciate your work in 
developing it!

Re: Auto-Organize Layout

[Matt Gilman]

+1 to adding capabilities that will allow users to build the desired layout
more efficiently. Allowing them to more easily align components,
snap-to-grid, lock, and bend connections would all fall into this category.

I'm a little indifferent to supporting an auto-layout feature. I've tried a
number of different options for creating an optimum layout of directed
graphs and the results are typically sub-par for this purpose. Some of the
layouts being described are very useful when analyzing a dataset and
learning about the relationships between the elements. However, I'm not
sure how applicable they would be for visualizing a data flow. Building a
simple top-down left-right auto layout for a cyclic graph would also yield
poor results in my opinion. Additionally, supporting a view that is not
representative of the underlying flow.xml is a departure from our current
design model.

In short, my preference would be to provide the tools for the users to
build the layout they want rather than provide auto layouts that may not be
helpful.

"it is sometimes too easy to mis-align processors by dragging them accidentally"
  Great point  I must admit I too do that.  Often in really important
demos.  I've gotten good at making jokes about it.  Probably should
have gotten good at submitting a JIRA :-)

I'd like to understand more about your other idea for emphasizing
processors which are more important.  I can understand the idea I
think but I'm worried about how we could make the user experience
worth the effort for the person signaling the emphasis to be of use
for the people consuming that detail.

Re: Auto-Organize Layout

[Elli Schwarz]

I also think that some way to help layout the flow would be very useful. One of 
the hardest parts of creating an easy to read workflow is the designing a good 
layout, and in many cases I simply want to be able to select a few processors 
and line them up (horizontally or vertically). Also, it is sometimes too easy 
to mis-align processors by dragging them accidentally. It would be nice if 
there would be a way to "lock" the layout of a group of selected processors so 
they can't be accidentally moved. Also, the ability to "undo" a layout change 
or save a layout (ie, just save the position of a group of selected processors) 
so that we can revert to it would also be helpful.

Another thing that could be helpful is a way to emphasize the more important 
processors, ie, the ones integral to the flow, as opposed to the many "PutFile" 
processors I have that are simply for logging (although I realize that 
sometimes a PutFile can be an integral part of a flow). I know I can select a 
group of processors and change the color, and also create a label to highlight 
a certain group of processors, but it might be nice to be able to make selected 
processors appear larger on the screen than others, to emphasize their 
importance. It is sometimes hard to follow the trail of a flow simply because 
there are many connections, so a way to highlight the "main" path might be 
useful.

I could see this being achieved by snapping the component to the same spot

Re: Auto-Organize Layout

[Ryan H]

I don't care so much about having it lined up, in this case (although
*OCD!*), more about knowing that I could view the data in a common-way on
any nifi, globally, if i choose to click a "view->auto-layout->up-down" or
"view->auto-layout->left-right".

Again, this doesn't overwrite flow.xml file.  Just a way to organize the
canvas using common alternate view(s).

Re: Auto-Organize Layout

[dan bress]

Maybe not exactly "auto-layout" but I would back a notion of having the
components snap to a coarser grain grid than what we currently have.
Sometimes I care a lot about having everything line up in the graph
horizontally and vertically, and it always takes a long time to achieve
this.

I could see this being achieved by snapping the component to the same spot
horizontally as the component above it when you move it underneath another
component.  Or some magical "auto snap" button that does its best to align
everything with its nearest neighbors.

Re: Auto-Organize Layout

[Ryan H]

I like your idea Rob, that would help with lining up relationships too
(straight lines).

On Matt's note, I don't think there should be a "standard" either, although
best practices are always out there.

On Matt's note of putting failures up above processes, we do that too.
Totally depends on who made the flow first.  Sometimes, people don't even
follow a convention in the same flow.xml file.

For these reasons, I'd recommend alternate views to the flow.

We have a couple projects that just allow you to rearrange a node-based
graph, based on your preference, hierarchy, circular, pyramid, etc.

Applying this to NiFi, having a couple different default auto-layout
options that you can swap your current view to, but NOT change the original
flow, would be nice.

It would let you walk into someone else's, potentially large, dataflow and
have a familiar way to view the flow.

Re: Auto-Organize Layout

[Rob Moran]

I agree with Matt's points. I was just replying with something similar
basically saying I think trying to set a standard would not be
well-received.

I believe what could be more useful are layout tools that would help users
place components to help achieve their preferred layouts. For example, the
ability to align (left, right, center) components
or horizontally/vertically distribute components evenly. Other features
such as snap-to and/or smart-guides could make it easier for users to
follow their organization's best practices when designing a flow.

Re: Auto-Organize Layout

[Matthew Clarke]

Ryan,

  Setting a standard is a difficult thing to do.  The complexity
that can exist in many flows would make enforcing a standard difficult. The
first example you provide of success to points right while failures point
up is not recommended. It would be better to have failures point down since
it is common to put labels over processor(s). Any relationships pointing up
would pass through these labels making both the relationship box and the
label hard to read.  It is often coomon to see flows designed with a
combination of left to right and top to bottom design.

Re: Auto-Organize Layout

[Ryan H]

Hi Rob,
Yea we did, it was at the end of the meeting.

I think it would be useful to have a couple default type views that
help standardize flow layout across the community.

For example, when we organize processors left-to-right, failure
relationships always point up, and success always point right.
Alternatively, when we organize processors up-and-down, failure
relationships always point left, and successes always point down.

Of course, in some of these scenarios there are processors that have
more than 1 success relationship, but that's when a good layout library
would come into play.

What do you think?

Ryan - I think we spoke briefly (at a very high level) about this at a
prior meetup. What alternate views did you have in mind, and in what ways
do you think they'd be useful?
