Things are working fine for Inserts and Updates to data. However, if a data row is deleted at the source.. How do i make NiFi Cache understand that this row no longer exists in the source and should be deleted from the Cache. I see a function "remove" in DistributedMapCacheClient.java .. How do i use the remove functionality?</P><P>Anyone having an idea please let me know.</P> Thu, 15 Dec 2016 20:48:29 GMT https://community.cloudera.com/t5/Support-Questions/How-to-delete-from-NiFi-DistributedMapCache/m-p/155349#M117788 anubhav_r_raika 2016-12-15T20:48:29Z https://community.cloudera.com/t5/Support-Questions/How-to-delete-from-NiFi-DistributedMapCache/m-p/155350#M117789 <P>Currently the remove() functionality is used by particular processors such as DetectDuplicate, GetHBase, etc. and is not exposed via a RemoveDistributedMapCache processor or anything like that.</P><P>I have <A target="_blank" href="https://community.hortonworks.com/articles/71837/working-with-a-nifi-distributedmapcache.html">written an article</A> that provides and describes a Groovy script I wrote to interact with the DistributedMapCacheServer from the command line, does that suit your needs?</P> Fri, 16 Dec 2016 00:30:39 GMT https://community.cloudera.com/t5/Support-Questions/How-to-delete-from-NiFi-DistributedMapCache/m-p/155350#M117789 mburgess 2016-12-16T00:30:39Z https://community.cloudera.com/t5/Support-Questions/How-to-delete-from-NiFi-DistributedMapCache/m-p/155351#M117790 <P>with your script, i wont even need to use Put and Fetch processors..
