Hi folks,
I’m using apache Cassandra 2.2.
Instance is configured with max_heap_size set at 16G, memtable_allocation_type
is offheap_objects – total available memory is 62G on the server.
There is nothing but Cassandra is running on my Linux server.
My Cassandra instance is consuming all availa
Hi Eax,
are you truncating/dropping tables between tests? Are your issues perhaps
related to that?
If you are, you should disable autoSnapshots and enable -DunsafeSystem=true
to make it run smoother.
kind regards,

you can look at these two files, to tune down the settings for test

Hello.
We are running integration tests, using real Cassandra (not a mock)
under Vagrant. MAX_HEAP_SIZE is set to 500M. As I discovered, lower
value causes 'out of memory' after some time.
Could memory usage be decreased somehow? Developers don't usually have
a lot of free RAM and performance obv

I have Cassandra server which has JVM setting -Xms4G -Xmx4G, but why top
reports 15G RES memory and 11G SHR memory usage? I understand that -Xmx4G
is only for the heap size. but it is strange that OS reports 2.5 times
memory usage. Are there a lot of memory used by JNI? Please help to explain
this.
