Nope. I added millions of records and several GB to the cluster while one node
was down, and then ran "nodetool flush system hints" on a couple of nodes that
were up, and system/hints has less than 200K in it.
Here’s the relevant part of "nodetool cfstats system.hints":
Keyspace: system
Read Count: 28572
Read Latency: 0.01806502869942601 ms.
Write Count: 351
Write Latency: 0.04547008547008547 ms.
Pending Tasks: 0
Table: hints
SSTable count: 1
Space used (live), bytes: 7446
Space used (total), bytes: 80062
SSTable Compression Ratio: 0.2651441528992549
Number of keys (estimate): 128
Memtable cell count: 1
Memtable data size, bytes: 1740
The hints are definitely not being stored.

Hi Robert ,
Maybe you need to flush your memtables to actually see the disk usage increase?
This applies to both hosts.
Cheers,

I have a cluster with RF=3. If I shut down one node, add a bunch of data to the
cluster, I don’t see a bunch of records added to system.hints. Also, du of
/var/lib/cassandra/data/system/hints of the nodes that are up shows that hints
aren’t being stored. When I start the down node, its data doesn’t grow until I
run repair, which then takes a really long time because it is significantly out
of date. Is there some magic setting I cannot find in the documentation to
enable hinted handoff? I’m running 2.0.11. Any insights would be greatly
appreciated.
Thanks
