Property
Default
Description
concurrent_writes
32
Generally writes are faster than reads. So we can
set this parameter on the higher side in comparison
to concurrent_reads.
memtable_total_space_in_mb
One third of JVM heap(disabled)
Total space allocated for memtables. Once exceed-
ing specified size Cassandra will flush the largest
memtable first onto disk.
commitlog_total_space_in_mb
32(32 bit JVM), 1024(64bit JVM)
Total space allocated commit log segments. Upon
reaching the specified limit, Cassandra flushes
memtables to claim space by removing the oldest
commit log first.
storage_port
7000
TCP port for internal communication between
nodes.
ssl_storage_port
7001
Used if client_encryption_options is enabled.
Address to bind and connect with other Cassandra
nodes.
listen_address
Localhost
Disabled(same as listen_address)
Broadcast address for other Cassandra nodes.
broadcast_address
internode_authenticator
AllowAllInternodeAuthenticator
IinternodeAuthenticator
interface im-
plementation for internode communication.
start_native_transport
False
CQL native transport for clients.
9042
CQL native transport port to connect with clients.
native_transport_port
Localhost
Thrift rpc address, client to connect with.
rpc_address
9160
Thrift rpc port for clients to communicate.
rpc_port
rpc_min_threads
16
Minimum number of thread for thrift rpc.
2147483647(Maximum 32-bit signed in-
teger)
Maximum number of threads for thrift rpc.
rpc_max_threads
Disabled
Enable if you want to set a limit of receiving sock-
et buffer size for thrift rpc.
rpc_recv_buff_size_in_bytes
Disabled
Enable if you want to set a limit of sending socket
buffer size for thrift rpc.
rpc_send_buff_size_in_bytes
False
If enabled, Cassandra will hard links flushed
sstables to backup directory under
data_file_directories/keyspace/backup directory.
incremental_backups
False
If enabled, will create snapshots before each com-
paction under the
data_file_directories/
keyspace/snapshots
directory.
snapshot_before_compaction
