| JVM_OPT_DISABLE_AUTH_CACHES_REMOTE_CONFIGURATION | To disable configuration via JMX of auth caches (such as those for credentials, permissions and roles). This will mean those config options can only be set (persistently) in cassandra.yaml and will require a restart for new values to take effect. | |
| JVM_OPT_FORCE_DEFAULT_INDEXING_PAGE_SIZE | To disable dynamic calculation of the page size used when indexing an entire partition (during initial index build/rebuild). If set to true, the page size will be fixed to the default of 10000 rows per page. | |
| JVM_OPT_PREFER_IPV4_STACK | Prefer binding to IPv4 network intefaces (when net.ipv6.bindv6only=1). See http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6342561 (short version: comment out this entry to enable IPv6 support). | True |
| JVM_OPT_EXPIRATION_DATE_OVERFLOW_POLICY | Defines how to handle INSERT requests with TTL exceeding the maximum supported expiration date. | |
| JVM_OPT_THREAD_PRIORITY_POLICY | allows lowering thread priority without being root on linux - probably not necessary on Windows but doesn't harm anything. | 42 |
| JVM_OPT_THREAD_STACK_SIZE | Per-thread stack size. | 256k |
| JVM_OPT_STRING_TABLE_SIZE | Larger interned string table, for gossip's benefit (CASSANDRA-6410) | 1000003 |
| JVM_OPT_SURVIVOR_RATIO | CMS Settings: SurvivorRatio | 8 |
| JVM_OPT_MAX_TENURING_THRESHOLD | CMS Settings: MaxTenuringThreshold | 1 |
| JVM_OPT_CMS_INITIATING_OCCUPANCY_FRACTION | CMS Settings: CMSInitiatingOccupancyFraction | 75 |
| JVM_OPT_CMS_WAIT_DURATION | CMS Settings: CMSWaitDuration | 10000 |
| JVM_OPT_NUMBER_OF_GC_LOG_FILES | GC logging options: NumberOfGCLogFiles | 10 |
| JVM_OPT_GC_LOG_FILE_SIZE | GC logging options: GCLOGFILESIZE | 10M |
| JVM_OPT_GC_LOG_DIRECTORY | GC logging options: GC_LOG_DIRECTORY | |
| JVM_OPT_PRINT_FLS_STATISTICS | GC logging options: PrintFLSStatistics | |
| JVM_OPT_CONC_GC_THREADS | By default, ConcGCThreads is 1/4 of ParallelGCThreads. Setting both to the same value can reduce STW durations. | |
| JVM_OPT_INITIATING_HEAP_OCCUPANCY_PERCENT | Save CPU time on large (>= 16GB) heaps by delaying region scanning until the heap is 70% full. The default in Hotspot 8u40 is 40%. | |
| JVM_OPT_MAX_GC_PAUSE_MILLIS | Main G1GC tunable: lowering the pause target will lower throughput and vise versa. | |
| JVM_OPT_G1R_SET_UPDATING_PAUSE_TIME_PERCENT | Have the JVM do less remembered set work during STW, instead preferring concurrent GC. Reduces p99.9 latency. | |
| CUSTOM_JVM_OPTIONS_BASE64 | Base64-encoded JVM options appended to jvm.options. | |
| POD_MANAGEMENT_POLICY | podManagementPolicy of the Cassandra Statefulset | OrderedReady |
| REPAIR_POD | Name of the pod on which 'nodetool repair' should be run. | |
| RECOVERY_CONTROLLER | Needs to be true for automatic failure recovery and node eviction | False |
| RECOVERY_CONTROLLER_DOCKER_IMAGE | Recovery controller Docker image. | mesosphere/kudo-cassandra-recovery:0.0.2-1.0.1 |
| RECOVERY_CONTROLLER_DOCKER_IMAGE_PULL_POLICY | Recovery controller Docker image pull policy. | Always |
| RECOVERY_CONTROLLER_CPU_MC | CPU request (in millicores) for the Recovery controller container. | 50 |
| RECOVERY_CONTROLLER_CPU_LIMIT_MC | CPU limit (in millicores) for the Recovery controller container. | 200 |
| RECOVERY_CONTROLLER_MEM_MIB | Memory request (in MiB) for the Recovery controller container. | 50 |
| RECOVERY_CONTROLLER_MEM_LIMIT_MIB | Memory limit (in MiB) for the Recovery controller container. | 256 |
