----------------------------------------
Thank you [~suma.shivaprasad] for understanding
{quote}if the aggregatorWrapper runnable runs before the enableAppAggregators
is called for that app during credential updates
{quote}
AggregatorImpl thread is infinite loop . And aggregation is notified on
interval or on application finish. So you are correct, if token renewed event
is not received before application finish then logs will be deleted. Also if
event is delayed when aggregator won't be found. But this case i feel very rare
. Since we should received new token in first heartbeat .
Additionally delayed deletion suggestion for those cases i had suggested. Will
handle in separate jira..
Any other suggestion ??
{quote}Applications dont get removed from invalidTokenApps except in
enableAppAggregators
{quote}
Nice catch, Will udpate in next patch.
