Koji Kawamura commented on NIFI-3216: ------------------------------------- Yes, we also need an optional property in the Wait processor to specify which count to check, if this is not specified, let it uses total count. > Add ability to wait for N signals to Wait/Notify processors > ----------------------------------------------------------- > > Key: NIFI-3216 > URL: https://issues.apache.org/jira/browse/NIFI-3216 > Project: Apache NiFi > Issue Type: Improvement > Affects Versions: 1.2.0 > Reporter: Bryan Bende > > The recently added Wait and Notify processors allow a flow file to be held at > the Wait processor until a signal is received in the Notify processor. It > would be nice to be able to wait for N signals before releasing. > One way this could be done is to have a property like "Signal Count" on the > Wait processor, and then count the keys in the cache starting with some > pattern, and release when the # of keys equals the signal count. > This would require the ability to get all the keys from the cache, or at > least get all keys matching a pattern: > https://issues.apache.org/jira/browse/NIFI-3214 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
