First 10 long running cache futures [total=1]

Hi Guru,

Hello!

The printed cache future contains some of this information, but it's hard
to decipher.

In this case, you are waiting for a node
1e36906c-fae5-49a3-b67a-9eed6ada7e4e. It will make sense to check its
thread dump.

thanks, are there any hints that can find/locate the operations that impact
the server?

Hello!

This means a cache operation takes longer to complete than usual, mostly
due to locking, node network unavailability, checkpoint, etc...
