Im not sure what is the difference with the MapCacheClientService but it should do the same job. Also be aware because of size limitation Nifi is not being published with all packages and in case you dont find services or processors that should be part of nifi , you probably need to download jar\nar pacakge from maven repositories and save to the Nifi Lib Folder:</SPAN></P><P><SPAN><A href="https://mvnrepository.com/artifact/org.apache.nifi/nifi-hazelcast-services-api-nar/2.0.0" target="_blank">https://mvnrepository.com/artifact/org.apache.nifi/nifi-hazelcast-services-api-nar/2.0.0</A></SPAN></P><P><SPAN><A href="https://mvnrepository.com/artifact/org.apache.nifi/nifi-distributed-cache-client-service-api" target="_blank">https://mvnrepository.com/artifact/org.apache.nifi/nifi-distributed-cache-client-service-api</A></SPAN></P><P><SPAN>If that helps please accept the solution.</SPAN></P><P><SPAN>Thanks</SPAN></P><P>&nbsp;</P> Wed, 04 Dec 2024 14:51:19 GMT https://community.cloudera.com/t5/Support-Questions/How-to-use-Notify-and-Wait-in-Apache-Nifi-version-2-0-0/m-p/398407#M250180 SAMSAL 2024-12-04T14:51:19Z https://community.cloudera.com/t5/Support-Questions/How-to-use-Notify-and-Wait-in-Apache-Nifi-version-2-0-0/m-p/398428#M250185 <P><a href="https://community.cloudera.com/t5/user/viewprofilepage/user-id/80381">@SAMSAL</a>&nbsp;MapCacheClientService provides the ability to communicate with a MapCacheServer.
