Since version 6.3.0 and 7.1.0. We have removed the ability to configure the connection's cache expiry via the connection user interface to give way to the new Atlassian cache2 library upgrade to support Data Center.
The cache expiry will have defaulted to 24 hours. If you need to configure the cache expiry for some reason. You still can do it by configuring the System Property(
net.customware.plugins.connector.salesforce.connection.<connectionId>.cacheExpiry). You should replace the <connectionId> placeholder with the connection that you are configuring.If you're administering the Jira Data Center. You will need to restart the Jira Data Center Cluster(Stop all the nodes in the cluster) for the cluster caches to pick up the configuration.
