the not entirely correct but very lightweight approach would be to look at the
size of the HintsColumnFamily in the system KS.
If you want an exact number use the functions on the HH MBean

Thanks for the quick reply, Mohit.Can we measure/monitor the size of
Hinted Handoffs? Would it be a good enough indicator of my back log?
Although we know when a network is flaky, we are interested in knowing how
much data is piling up in local DC that needs to be transferred.
Greatly apprec
As far as I know Cassandra doesn't use internal queueing mechanism specific
to replication. Cassandra sends the write the remote DC and after that it's
upto the tcp/ip stack to deal with buffering. If requests starts to timeout
Cassandra would use HH upto certain time. For longer outage you would h
Hi,
We have multi DC Cassandra ring with 2 DCs setup. We use LOCAL_QUORUM for
writes and reads. The network we have seen between the DC is sometimes
flaky lasting few minutes to few 10 of minutes.
I wanted to know what is the best way to measure/monitor either the lag or
