worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,

where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the

modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and

as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade

7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

# The more tokens, relative to other nodes, the larger the proportion of data

#
# If you leave this unspecified, Cassandra will use the default of 1 token for legacy compatibility,

# 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.

# This sets the number of memtable flush writer threads per disk

# Memtable flushing is more CPU efficient than memtable ingest and a single thread
# can keep up with the ingest rate of a whole server on a single fast disk

# This means that two memtables can be flushed concurrently to the single data directory.
# If you have multiple data directories the default is one memtable flushing at a time
# but the flush will use a thread per data directory so you will get two or more writers.
#
# Two is generally enough to flush on a fast disk [array] mounted as a single data directory.
# Adding more flush writers will result in smaller more frequent flushes that introduce more
# compaction overhead.

# per thread, and that will correspond to your use of virtual memory (but physical memory
# may be limited depending on use of stack space).

# 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
# IEndpointSnitch. The snitch has two functions:
#
# - it teaches Cassandra enough about your network topology to route
# requests efficiently
# - 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)
#
# CASSANDRA WILL NOT ALLOW YOU TO SWITCH TO AN INCOMPATIBLE SNITCH
# ONCE DATA IS INSERTED INTO THE CLUSTER. This would cause data loss.
# This means that if you start with the default SimpleSnitch, which
# locates every node on "rack1" in "datacenter1", your only options
# if you need to add another datacenter are GossipingPropertyFileSnitch
# (and the older PFS). From there, if you want to migrate to an
# incompatible snitch like Ec2Snitch you can do it by adding new nodes
# under Ec2Snitch (which will locate them in a new "datacenter") and
# decommissioning the old ones.
#
# Out of the box, Cassandra provides:
#
# 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.
#
# You can use a custom Snitch by setting this to the full class name
# of the snitch, which will be assumed to be on your classpath.

# Coalescing Strategies #
# Coalescing multiples messages turns out to significantly boost message processing throughput (think doubling or more).
# On bare metal, the floor for packet processing throughput is high enough that many applications won't notice, but in
# virtualized environments, the point at which an application can be bound by network packet processing can be
# surprisingly low compared to the throughput of task processing that is possible inside a VM. It's not that bare metal
# doesn't benefit from coalescing messages, it's that the number of packets a bare metal network interface can process
# is sufficient for many applications such that no load starvation is experienced even without coalescing.
# There are other benefits to coalescing network messages that are harder to isolate with a simple metric like messages
# per second. By coalescing multiple tasks together, a network thread can process multiple messages for the cost of one
# trip to read from a socket, and all the task submission work can be done at the same time reducing context switching
# and increasing cache friendliness of network message processing.
# See CASSANDRA-8692 for details.

#
# Two is generally enough to flush on a fast disk [array] mounted as a single data directory.
# Adding more flush writers will result in smaller more frequent flushes that introduce more
# compaction overhead.

# 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
# IEndpointSnitch. The snitch has two functions:
#
# - it teaches Cassandra enough about your network topology to route
# requests efficiently
# - 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)
#
# CASSANDRA WILL NOT ALLOW YOU TO SWITCH TO AN INCOMPATIBLE SNITCH
# ONCE DATA IS INSERTED INTO THE CLUSTER. This would cause data loss.
# This means that if you start with the default SimpleSnitch, which
# locates every node on "rack1" in "datacenter1", your only options
# if you need to add another datacenter are GossipingPropertyFileSnitch
# (and the older PFS). From there, if you want to migrate to an
# incompatible snitch like Ec2Snitch you can do it by adding new nodes
# under Ec2Snitch (which will locate them in a new "datacenter") and
# decommissioning the old ones.
#
# Out of the box, Cassandra provides:
#
# 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.
#
# You can use a custom Snitch by setting this to the full class name
# of the snitch, which will be assumed to be on your classpath.

# Coalescing Strategies #
# Coalescing multiples messages turns out to significantly boost message processing throughput (think doubling or more).
# On bare metal, the floor for packet processing throughput is high enough that many applications won't notice, but in
# virtualized environments, the point at which an application can be bound by network packet processing can be
# surprisingly low compared to the throughput of task processing that is possible inside a VM. It's not that bare metal
# doesn't benefit from coalescing messages, it's that the number of packets a bare metal network interface can process
# is sufficient for many applications such that no load starvation is experienced even without coalescing.
# There are other benefits to coalescing network messages that are harder to isolate with a simple metric like messages
# per second. By coalescing multiple tasks together, a network thread can process multiple messages for the cost of one
# trip to read from a socket, and all the task submission work can be done at the same time reducing context switching
# and increasing cache friendliness of network message processing.
# See CASSANDRA-8692 for details.

# will be appropriate. A smaller value could potentially expire messages slightly sooner at the expense of more CPU

# 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

# Uncomment any of the following properties to enable specific startup parameters
# In a multi-instance deployment, multiple Cassandra instances will independently assume that all
# CPU processors are available to it. This setting allows you to specify a smaller set of processors
# 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

#-Dcassandra.triggers_dir=directory
# For testing new compaction and compression strategies. It allows you to experiment with different
# strategies and benchmark write performance differences without affecting the production workload.
#-Dcassandra.write_survey=true
# 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.
#-Dcassandra.disable_auth_caches_remote_configuration=true

# Do only change the default value, if you really have more prepared statements than
# fit in the cache. In most cases it is not neccessary to change this value.
# Constantly re-preparing statements is a performance penalty.

# Default value ("auto") is 1/256th of the heap or 10MB, whichever is greater

thrift_prepared_statements_cache_size_mb:
# Maximum size of the key cache in memory.
#
# 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.

# 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

# Coalescing Strategies #
# Coalescing multiples messages turns out to significantly boost message processing throughput (think doubling or more).
# On bare metal, the floor for packet processing throughput is high enough that many applications won't notice, but in
# virtualized environments, the point at which an application can be bound by network packet processing can be
# surprisingly low compared to the throughput of task processing that is possible inside a VM. It's not that bare metal
# doesn't benefit from coalescing messages, it's that the number of packets a bare metal network interface can process
# is sufficient for many applications such that no load starvation is experienced even without coalescing.
# There are other benefits to coalescing network messages that are harder to isolate with a simple metric like messages
# per second. By coalescing multiple tasks together, a network thread can process multiple messages for the cost of one
# trip to read from a socket, and all the task submission work can be done at the same time reducing context switching
# and increasing cache friendliness of network message processing.
# See CASSANDRA-8692 for details.
# Strategy to use for coalescing messages in OutboundTcpConnection.
# Can be fixed, movingaverage, timehorizon, disabled (default).
# You can also specify a subclass of CoalescingStrategies.CoalescingStrategy by name.
# otc_coalescing_strategy: DISABLED
# How many microseconds to wait for coalescing. For fixed strategy this is the amount of time after the first
# message is received before it will be sent with any accompanying messages. For moving average this is the
# maximum amount of time that will be waited as well as the interval at which messages must arrive on average
# for coalescing to be enabled.
# otc_coalescing_window_us: 200
# Do not try to coalesce messages if we already got that many messages. This should be more than 2 and less than 128.
# otc_coalescing_enough_coalesced_messages: 8
# How many milliseconds to wait between two expiration runs on the backlog (queue) of the OutboundTcpConnection.
# Expiration is done if messages are piling up in the backlog. Droppable messages are expired to free the memory
# taken by expired messages. The interval should be between 0 and 1000, and in most installations the default value
# will be appropriate. A smaller value could potentially expire messages slightly sooner at the expense of more CPU
# time and queue contention while iterating the backlog of messages.
# An interval of 0 disables any wait time, which is the behavior of former Cassandra versions.

# 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.
-Xms{{ cassandra_heap_size }}
-Xmx{{ cassandra_heap_size }}
# 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
