Subject [jira] [Commented] (NIFI-6873) Add support to import versioned flow
Date Tue, 11 Feb 2020 19:48:00 GMT


ASF subversion and git services commented on NIFI-6873:

Commit 62606ff89a5947197fc0a92adae9e7a5104ca2b7 in nifi's branch refs/heads/master from Joe
[;h=62606ff ]

NIFI-6873: Added support for replacing a process group
 - decoupled flow update request behavior from VersionsResource into new abstract FlowUpdateResource
 - added replace process group functionality in ProcessGroupResource
 - parameterized FlowUpdateResource and created entity hierarchies to allow for maximum code
sharing across different update types
 - refactored flow update methods to make use of commonality across different update types
whenever possible
 - fixed issues in StandardProcessGroup verify update methods where same components existed
in different ancestry chains but were considered a match when they shouldn't be
 - improved StandardProcessGroup to properly match up components on update using generated
versioned component ids, when necessary to allow for update flow to efficiently match common
components on flow import

This closes #4023.

> When integrating with a NiFi Registry, NiFi can generate versioned flows to store in
the registry. We should also allow these versioned flows to be imported directly.
