Hi Denis,
I have enabled the INFO logs and tried to delete a cache. Please find the logs below: Aug 20, 2019 11:00:17 AM org.apache.ignite.logger.java.JavaLogger info INFO: Stopped cache [cacheName=Person] cache deleted in:17280 ms ---->>> This is a print statement from our code Aug 20, 2019 11:00:17 AM org.apache.ignite.logger.java.JavaLogger info INFO: Completed partition exchange [localNode=90c11807-ac10-43a6-b7b6-605d5c07314d, exchange=GridDhtPartitionsExchangeFuture [topVer=AffinityTopologyVersion [topVer=5891, minorTopVer=2], evt=DISCOVERY_CUSTOM_EVT, evtNode=TcpDiscoveryNode [id=90c11807-ac10-43a6-b7b6-605d5c07314d, addrs=[0:0:0:0:0:0:0:1%lo, 127.0.0.1, 192.168.1.116, 192.168.1.249], sockAddrs=[device-shravya-hp/192.168.1.249:0, /0:0:0:0:0:0:0:1%lo:0, /127.0.0.1:0, /192.168.1.116:0], discPort=0, order=5890, intOrder=0, lastExchangeTime=1566278969558, loc=true, ver=2.7.0#20181201-sha1:256ae401, isClient=true], done=true], topVer=AffinityTopologyVersion [topVer=5891, minorTopVer=2], durationFromInit=16882] Aug 20, 2019 11:00:17 AM org.apache.ignite.logger.java.JavaLogger info It looks like partition exchange is taking more time. How can this be avoided? What is the importance of Partition exchange?

How many nodes do you have in your cluster? If you are running in PARTITONED mode then some exchange of information will occur. More details here: https://apacheignite.readme.io/docs/cache-modes Do you have a reproducer project?

Why is it taking more execution time? Will there be any exchange of cache information among the nodes whenever a cache is deleted? Is there any way in which, the execution time can be optimized?
