Hi all,
Apologies for the cross-post. In case you're in the SF Bay Area, Instagram is
hosting a meetup. Interesting talks on Cassandra Traffic management, Cassandra
on Kubernetes. See details in the attached link -
Are you running any nodetool commands during that period? IIRC, this is a log
entry emitted by the BufferPool. It may be harm unless it's happening very
often or logging a OOM.

Hey Kunal,
Can you add more details about the size of data, read/write throughput, what

Hey Kunal,
Can you add more details about the size of data, read/write throughput, what
are your latency expectations, etc? What do you mean by "performance" issue
with replication? Without these details it's a bit tough to answer your
questions.

Would it be possible for you to take a thread dump & logs and share them?

Providing logs or more technical information might be helpful. If it is
cassandra-lucene related issue, perhaps it'll be better to open a issue in
their github repo?

I've worked with both databases. They're suitable for different use-cases. If
you look at the CAP theorem; HBase is CP while Cassandra is a AP. If we talk
about a specific use-case, it'll be easier to discuss.

It doesn't look like there is an existing Jira. It would be helpful if you
could create one with as much information as possible. Can you reduce this
issue to a short, repeatable set of steps that we can reproduce? That'll be
helpful to debug this problem.

If you're working in a different keyspace, I don't anticipate any issues. Have
you attempted one in a test cluster? :)

As Jeff mentioned that you need to provide more information. There are no known
