Manual Refresh of Cached Map

[Anirvan Majumdar]

Hello,

I had recently set up a 4 node distributed cache using HZ, and it's been working flawlessly. I also got myself a trial license to monitor the caches through mancenter. So far, the experience has been really good, and the data and actions available through mancenter makes it really simple to understand the performance of the cache.

Recently, I encountered a situation whereby I wanted to refresh the data in one of the distributed maps without having to restart the nodes. I accessed the map through the mancenter and clicked on the "Configuration" button. However, I couldn't find an option to clear the map data in the dialog.

I was wondering whether there's any way to do this without having to restart all the nodes?

Thanks,

You can send following script to one of the nodes:

var map = hazelcast.getMap('customers');

map.clear();
