I am starting a stress test using hector on 6 node machine 4GB heap and 12
core. In hectore readme this is what I got by default:
create keyspace StressKeyspace
with replication_factor = 3
and placement_strategy = 'org.apache.cassandra.locator.SimpleStrategy';
use StressKeyspace;
drop column family StressStandard;
create column family StressStandard
with comparator = UTF8Type
and keys_cached = 10000
and memtable_flush_after = 1440
and memtable_throughput = 32;
Are these good values? I was thinking of highher keys_cached but not sure if
it's in bytes or no of keys.
Also not sure how to tune memtable values.
I have set concurrent_readers to 32 and writers to 48.
Can someone please help me with good values that I can start this test with?
Also, any other suggested values that I need to change?
Thanks
