Hi, First of all, I don’t know why they get delivered so slowly.
However, if your gc grace seconds is the default 10 days then those hints from May are not needed and could/should be truncated. If the hint delivery is causing problems, then one option is that you could just disable it and rely on periodic repair doing its job and getting the data synchronized. Now my question to you: Do you have repairs running periodically across the cluster and actually succeeding if the connection is flaky?

A DC1 node is storing large number of hints for DC2 nodes (we are facing connection timeout issues). The problem is that the hint files which are created on DC1 are not getting deleted after the 3 hour window. Hints are now being stored as flat files in the Cassandra home directory and I can see that old hints are being deleted but at a very slow pace. It still contains hints from May. max_hint_window_in_ms: 10800000 max_hints_delivery_threads: 2 Why do you suppose this is happening? Any suggestions or recommendations would be much appreciated. Thanks for your time. Meg Mara
