Hi Ya sure - The contents of my file foo.yaml file are as follows: keyspace: benchmark table: foo insert: partitions: fixed(1) columnspec: - name: field1 size: fixed(10) - name: field2 size: fixed(11) population: fixed(1) - name: field3 size: fixed(10) - name: field4

Re: cassandra OOM

To add some contribution to this thread, we have seen both cases. CMS easily outperforming G1 for the same Heapsize and the inverse too. On the same cluster different workloads (datacenter based) we have both collectors because of performance based on the workload. It would be good to colect this

RE: cassandra OOM

We have seen much better stability (and MUCH less GC pauses) from G1 with a variety of heap sizes. I don’t even consider CMS any more. Sean Durity From: Gopal, Dhruva [mailto:dhruva.go...@aspect.com] Sent: Tuesday, April 04, 2017 5:34 PM To: user@cassandra.apache.org Subject: Re: cassandra OOM

Re: Will query on PK read entire partition?

Hi, if you provide primary key C* will not scan whole partition, but will bloom filter to determinate SSTable: Cassandra uses Bloom filters to determine whether an SSTable has data for a particular row. Bloom filters are unused for range scans, but are used for index scans. Best

Re: Cassandra Cluster Doubts

Hi Luis, I don't thinks it's possible to achieve this by custom Snitch. As far as I understand Snitch only provides cluster topology, and connectivity is done by another component/layer. And each cluster node should be able to connect to every other node. So I would keep with Michael's

Thanks Zhao Yang, > Could you try some jvm tool to find out which thread are allocating memory or gc? maybe the migration stage thread.. I use Cassandra Cluster Manager to locally reproduce the issue. I tried to use VisualVM to find out which threads are allocating memory, but VisualVM does not
