Hi!
I have the following keyspaces
cqlsh> SELECT * FROM system.schema_keyspaces;
keyspace_name | durable_writes |
strategy_class |
strategy_options
---------------+----------------+---------------------------------------------+----------------------------
system | True |
org.apache.cassandra.locator.LocalStrategy | {}
system_traces | False |
org.apache.cassandra.locator.SimpleStrategy | {"replication_factor":"2"}
a1_ks | False |
org.apache.cassandra.locator.SimpleStrategy | {"replication_factor":"1"}
I have two disks. Data directory is on sda. Commitlog is on sdb.
I do 100% writes into a1_ks.user_table .
Watching IO activities I noticed that C* write something (mutations)
into commitlog. But it's strange because I disabled durable writes for
a1_ks.
May be it's system activities and they are flushed into commitlog?
