The Apache Cassandra ring nodes require periodic maintenance to ensure consistency across all
nodes. To perform this maintenance, use the Cassandra "nodetool -h localhost repair" command.
In a single-region or single-data-center Apigee installation, use the command "nodetool -h localhost repair " on one
Cassandra node to ensure consistency across all nodes in the ring. In a multi-region or
multi-data-center Apigee installation, use "nodetool -h localhost repair -pr" on every
node in the ring (across all regions or data centers).
For more information, see the following resources:
Cassandra logs are stored in the /opt/apigee/var/log/cassandra directory on
each node. By default, a maximum of 50 log files, each with a maximum size of 20 MB, can be
created; once this limit is reached older logs are deleted when newer logs are created.
If you should find that Cassandra log files are taking up excessive space, you can modify the
amount of space allocated for log files by editing the log4j settings.
Edit /opt/apigee/customer/application/cassandra.properties
to set the following properties. If that file does not exist, create it: conf_log4j-server_log4j.appender.r.maxfilesize=20MB
# max file size
conf_log4j-server_log4j.appender.r.maxbackupindex=50 # max open files
Restart Cassandra by using the commands: $
/opt/apigee/apigee-service/bin/apigee-service apigee-cassandra restart
