# sync -> One thread per thrift connection. For a very large number of clients, memory
|

# will be your limiting factor. On a 64 bit JVM, 180KB is the minimum stack size
|

# 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.

# 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

# 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.

# 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.

#-XX:+UseG1GC

## 200ms is the JVM default and lowest viable setting

# Otherwise equal to the number of cores when 8 or less.

# Machines with > 10 cores should try setting these to <= full cores.
