# This defines the number of tokens randomly assigned to this node on the ring
# The more tokens, relative to other nodes, the larger the proportion of data
# that this node will store. You probably want all nodes to have the same number
# of tokens assuming they have equal hardware capability.
#
# If you leave this unspecified, Cassandra will use the default of 1 token for legacy compatibility,
# and will use the initial_token as described below.
#
# Specifying initial_token will override this setting on the node's initial start,
# on subsequent starts, this setting will apply even if initial token is set.

# If you already have a cluster with 1 token per node, and wish to migrate to
# multiple tokens per node, see http://wiki.apache.org/cassandra/Operations

# The load assigned to each node will be close to proportional to its number of
# vnodes.

# initial_token allows you to specify tokens manually. While you can use # it with

# Out of the box, Cassandra provides org.apache.cassandra.auth.CassandraRoleManager,

#
# Each key cache hit saves 1 seek and each row cache hit saves 2 seeks at the
# minimum, sometimes more. The key cache is fairly tiny for the amount of
# time it saves, so it's worthwhile to use it at large numbers.
# The row cache saves even more time, but must contain the entire row,
# so it is extremely space-intensive. It's best to only use the
# row cache if you have hot rows or static rows.
#
# NOTE: if you reduce the size, you may not get you hottest keys loaded on startup.
#
# Default value is empty to make it "auto" (min(5% of Heap (in MB), 100MB)). Set to 0 to disable key cache.
key_cache_size_in_mb:

#
# Default is 14400 or 4 hours.

# in previous releases of Cassandra.
# row_cache_class_name: org.apache.cassandra.cache.OHCProvider
# Maximum size of the row cache in memory.
# Please note that OHC cache implementation requires some additional off-heap memory to manage
# the map structures and some in-flight memory during operations before/after cache entries can be
# accounted against the cache capacity. This overhead is usually small compared to the whole capacity.
# Do not specify more memory that the system can afford in the worst usual situation and leave some
# headroom for OS block level cache. Do never allow your system to swap.
#
# Default value is 0, to disable row caching.
row_cache_size_in_mb: 0
# Duration in seconds after which Cassandra should save the row cache.
# Caches are saved to saved_caches_directory as specified in this configuration file.
#
# Saved caches greatly improve cold-start speeds, and is relatively cheap in

# has limited use.
#
# Default is 0 to disable saving the row cache.
row_cache_save_period: 0
# Number of keys from the row cache to save.
# Specify 0 (which is the default), meaning all keys are going to be saved
# row_cache_keys_to_save: 100
# Maximum size of the counter cache in memory.
#
# Counter cache helps to reduce counter locks' contention for hot counter cells.
# In case of RF = 1 a counter cache hit will cause Cassandra to skip the read before
# write entirely. With RF > 1 a counter cache hit will still help to reduce the duration
# of the lock hold, helping with hot counter cell updates, but will not allow skipping
# the read entirely. Only the local (clock, count) tuple of a counter cell is kept

# Cassandra provides two out-of-the-box options for the RPC Server:
#
# sync -> One thread per thrift connection. For a very large number of clients, memory

# per thread, and that will correspond to your use of virtual memory (but physical memory
# may be limited depending on use of stack space).
#
# hsha -> Stands for "half synchronous, half asynchronous." All thrift clients are handled
# asynchronously using a small number of threads that does not vary with the amount
# of thrift clients (and thus scales well to many clients). The rpc requests are still
# synchronous (one thread per active request). If hsha is selected then it is essential
# that rpc_max_threads is changed from the default value of unlimited.
#
# The default is sync because on Windows hsha is about 30% slower. On Linux,
# sync/hsha performance is about the same, with hsha of course using less memory.

# endpoint_snitch -- Set this to a class that implements

# - it teaches Cassandra enough about your network topology to route

# - it allows Cassandra to spread replicas around your cluster to avoid
# correlated failures. It does this by grouping machines into
# "datacenters" and "racks." Cassandra will do its best not to have
# more than one replica on the same "rack" (which may not actually
# be a physical location)
#
# IF YOU CHANGE THE SNITCH AFTER DATA IS INSERTED INTO THE CLUSTER,
# YOU MUST RUN A FULL REPAIR, SINCE THE SNITCH AFFECTS WHERE REPLICAS
# ARE PLACED.
#
# IF THE RACK A REPLICA IS PLACED IN CHANGES AFTER THE REPLICA HAS BEEN

# - SimpleSnitch:
# Treats Strategy order as proximity. This can improve cache
# locality when disabling read repair. Only appropriate for
# single-datacenter deployments.
# - GossipingPropertyFileSnitch
# This should be your go-to snitch for production use. The rack
# and datacenter for the local node are defined in
# cassandra-rackdc.properties and propagated to other nodes via
# gossip. If cassandra-topology.properties exists, it is used as a
# fallback, allowing migration from the PropertyFileSnitch.
# - PropertyFileSnitch:
# Proximity is determined by rack and data center, which are
# explicitly configured in cassandra-topology.properties.
# - Ec2Snitch:
# Appropriate for EC2 deployments in a single Region. Loads Region
# and Availability Zone information from the EC2 API. The Region is
# treated as the datacenter, and the Availability Zone as the rack.
# Only private IPs are used, so this will not work across multiple
# Regions.
# - Ec2MultiRegionSnitch:
# Uses public IPs as broadcast_address to allow cross-region
# connectivity. (Thus, you should set seed addresses to the public
# IP as well.) You will need to open the storage_port or
# ssl_storage_port on the public IP firewall. (For intra-Region
# traffic, Cassandra will switch to the private IP after
# establishing a connection.)
# - RackInferringSnitch:
# Proximity is determined by rack and data center, which are
# assumed to correspond to the 3rd and 2nd octet of each node's IP
# address, respectively. Unless this happens to match your
# deployment conventions, this is best used as an example of
# writing a custom Snitch class and is provided in that spirit.

# STARTUP PARAMETERS #
######################
# Uncomment any of the following properties to enable specific startup parameters
# In a multi-instance deployment, multiple Cassandra instances will independently assume that all

# and perhaps have affinity.
#-Dcassandra.available_processors=number_of_processors
# The directory location of the cassandra.yaml file.
#-Dcassandra.config=directory
# Sets the initial partitioner token for a node the first time the node is started.
#-Dcassandra.initial_token=token
# Set to false to start Cassandra on a node but not have the node join the cluster.
#-Dcassandra.join_ring=true|false
# Set to false to clear all gossip state for the node on restart. Use when you have changed node
# information in cassandra.yaml (such as listen_address).
#-Dcassandra.load_ring_state=true|false
# Enable pluggable metrics reporter. See Pluggable metrics reporting in Cassandra 2.0.2.
#-Dcassandra.metricsReporterConfigFile=file
# Set the port on which the CQL native transport listens for clients. (Default: 9042)
#-Dcassandra.native_transport_port=port
# Overrides the partitioner. (Default: org.apache.cassandra.dht.Murmur3Partitioner)
#-Dcassandra.partitioner=partitioner
# To replace a node that has died, restart a new node in its place specifying the address of the
# dead node. The new node must not have any data in its data directory, that is, it must be in the
# same state as before bootstrapping.
#-Dcassandra.replace_address=listen_address or broadcast_address of dead node
# Allow restoring specific tables from an archived commit log.
#-Dcassandra.replayList=table
# Allows overriding of the default RING_DELAY (1000ms), which is the amount of time a node waits
# before joining the ring.
#-Dcassandra.ring_delay_ms=ms
# Set the port for the Thrift RPC service, which is used for client connections. (Default: 9160)

#-Dcassandra.disable_auth_caches_remote_configuration=true
########################
# GENERAL JVM SETTINGS #
########################
# enable assertions. disabling this in production will give a modest
# performance benefit (around 5%).
-ea
# enable thread priorities, primarily so we can give periodic tasks
# a lower priority to avoid interfering with client workload
-XX:+UseThreadPriorities
# allows lowering thread priority without being root on linux - probably
# not necessary on Windows but doesn't harm anything.
# see http://tech.stolsvik.com/2010/01/linux-java-thread-priorities-workar
-XX:ThreadPriorityPolicy=42
# Enable heap-dump if there's an OOM
-XX:+HeapDumpOnOutOfMemoryError
# Per-thread stack size.
-Xss256k
# Larger interned string table, for gossip's benefit (CASSANDRA-6410)
-XX:StringTableSize=1000003
# Make sure all memory is faulted and zeroed on startup.
# This helps prevent soft faults in containers and makes
# transparent hugepage allocation more effective.
-XX:+AlwaysPreTouch
# Disable biased locking as it does not benefit Cassandra.
-XX:-UseBiasedLocking
# Enable thread-local allocation blocks and allow the JVM to automatically
# resize them at runtime.
-XX:+UseTLAB
-XX:+ResizeTLAB
# http://www.evanjones.ca/jvm-mmap-pause.html
-XX:+PerfDisableSharedMem
# 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).
-Djava.net.preferIPv4Stack=true
### Debug options
# uncomment to enable flight recorder
#-XX:+UnlockCommercialFeatures
#-XX:+FlightRecorder
# uncomment to have Cassandra JVM listen for remote debuggers/profilers on port 1414
#-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=1414
# uncomment to have Cassandra JVM log internal method compilation (developers only)
#-XX:+UnlockDiagnosticVMOptions
#-XX:+LogCompilation
#################
# HEAP SETTINGS #
#################
# Heap size is automatically calculated by cassandra-env based on this
# formula: max(min(1/2 ram, 1024MB), min(1/4 ram, 8GB))
# That is:
# - calculate 1/2 ram and cap to 1024MB
# - calculate 1/4 ram and cap to 8192MB
# - pick the max
#
# For production use you may wish to adjust this for your environment.
# If that's the case, uncomment the -Xmx and Xms options below to override the
# automatic calculation of JVM heap memory.
#
# It is recommended to set min (-Xms) and max (-Xmx) heap sizes to
# the same value to avoid stop-the-world GC pauses during resize, and
# so that we can lock the heap in memory on startup to prevent any
# of it from being swapped out.
#-Xms4G
#-Xmx4G
# Young generation size is automatically calculated by cassandra-env
# based on this formula: min(100 * num_cores, 1/4 * heap size)
#
# The main trade-off for the young generation is that the larger it
# is, the longer GC pause times will be. The shorter it is, the more
# expensive GC will be (usually).
#
# It is not recommended to set the young generation size if using the
# G1 GC, since that will override the target pause-time goal.
# More info: http://www.oracle.com/technetwork/articles/java/g1gc-1984535.html
#
# The example below assumes a modern 8-core+ machine for decent
# times. If in doubt, and if you do not particularly want to tweak, go
# 100 MB per physical CPU core.
#-Xmn800M

# GC SETTINGS #
#################
### CMS Settings
#-XX:+UseParNewGC
#-XX:+UseConcMarkSweepGC
#-XX:+CMSParallelRemarkEnabled
#-XX:SurvivorRatio=8
#-XX:MaxTenuringThreshold=1
#-XX:CMSInitiatingOccupancyFraction=75
#-XX:+UseCMSInitiatingOccupancyOnly
#-XX:CMSWaitDuration=10000
#-XX:+CMSParallelInitialMarkEnabled
#-XX:+CMSEdenChunksRecordAlways
# some JVMs will fill up their heap when accessed via JMX, see CASSANDRA-6541
#-XX:+CMSClassUnloadingEnabled
### G1 Settings (experimental, comment previous section and uncomment section below to enable)
## Use the Hotspot garbage-first collector.
-XX:+UseG1GC
#
## Have the JVM do less remembered set work during STW, instead
## preferring concurrent GC. Reduces p99.9 latency.
-XX:G1RSetUpdatingPauseTimePercent=5
#
## Main G1GC tunable: lowering the pause target will lower throughput and vise versa.
## 200ms is the JVM default and lowest viable setting
## 1000ms increases throughput. Keep it smaller than the timeouts in cassandra.yaml.
#-XX:MaxGCPauseMillis=500
## Optional G1 Settings
# Save CPU time on large (>= 16GB) heaps by delaying region scanning
# until the heap is 70% full. The default in Hotspot 8u40 is 40%.
#-XX:InitiatingHeapOccupancyPercent=70
# For systems with > 8 cores, the default ParallelGCThreads is 5/8 the number of logical cores.
# Otherwise equal to the number of cores when 8 or less.
# Machines with > 10 cores should try setting these to <= full cores.
#-XX:ParallelGCThreads=16
# By default, ConcGCThreads is 1/4 of ParallelGCThreads.
# Setting both to the same value can reduce STW durations.
#-XX:ConcGCThreads=16
### GC logging options -- uncomment to enable
