Mark Payne commented on NIFI-2458:
----------------------------------
So the interesting bit here is that we have optimized the query so that it
already just holds the last 1000 events or so in memory and it just immediately
returns those. Typically what I see is that the majority of the time spent on
that initial query is the network traffic of pulling those events back. There
is a JIRA (https://issues.apache.org/jira/browse/NIFI-1135) that addresses this
by pulling back 'summaries' of the events (only those things shown in the
table) instead of the entire events, which include all attributes, etc. of each
event. That is slated for 1.1.0 and I think will make this significantly better.

> I right-clicked on a Processor and choose to view provenance events. I then
> clicked Cancel on the progress bar dialog. I then clicked 'search' and added
> a new parameter to the search (added a value for 'Relationship'). When I
> click Search, I get an error message: Message body is malformed. Unable to
> map into expected format.
