9-5
The following cluster properties set the default values for the "Additional Properties" in the Manage Cassandra Connections task.
Refer to "Time Units" under Cluster Properties for a list of the valid time units that you can use for time-related properties.
Property
Description
cassandra.maxConnectionCacheAge
The maximum age of cached Cassandra connections. Value is a time unit. Enter '0' for no limit.
Default:
0
cassandra.maxConnectionCacheIdleTime
The maximum time a cached Cassandra connection can remain idle before being purged. Value is a time unit. Enter '0' for no limit.
Default:
30m
cassandra.maxConnectionCacheSize
The maximum number of cached Cassandra connections. Enter '0' for no caching.
Default:
20
Use this setting carefully, as an overly large cache can affect performance.
cassandra.maxSimultaneousRequests
PerHostThreshold
The maximum number of simultaneous requests per Cassandra host. The driver uses a single connection for each LOCAL or REMOTE host.
Default:
1024
(hostDistance=LOCAL);
256
(hostDistance=REMOTE)
cassandra.hostDistance
Determines the distance to the specified Cassandra host. Valid values: IGNORED, LOCAL, REMOTE
Default:
LOCAL
cassandra.keepAlive
Sets the java.net.SocketOptions.SO_KEEPALIVE option for the Cassandra connection.
cassandra.fetchSize
Sets the default fetch size for queries that do not explicitly set a fetch size. The fetch size determines the number of records retrieved in a single round trip to the Cassandra server. To disable paging, set the fetch size to 2147483647.
Default:
5000
cassandra.maxRecords
Sets the default maximum number of records the Perform Cassandra Query assertion will return from querying the Cassandra server.
Default:
10
cassandra.connectTimeoutMillis
The connect timeout in milliseconds for the underlying Netty channel.
Default:
5000
(milliseconds)
cassandra.readTimeoutMillis
Defines the amount of time in milliseconds the driver waits for a given Cassandra node to answer a query before timing out.
Default:
12000
(milliseconds)
cassandra.reuseAddress
Whether to allow the same port to be bound to multiple times. Corresponds to java.net.SocketOptions.SO_REUSEADDR for the Cassandra connection.
cassandra.receiveBufferSize
A hint on the size of the buffer that is used to receive data. Corresponds to java.net.SocketOptions.SO_RCVBUF for the Cassandra connection. Minimum is 0.
cassandra.sendBufferSize
A hint on the size of the buffer that is used to send data. Corresponds to java.net.SocketOptions.SO_SNDBUF for the Cassandra connection. Minimum is 0.
cassandra.soLinger
When specified, disables the immediate return from a call to close() on a TCP socket. Corresponds to java.net.SocketOptions.SO_LINGER for the Cassandra connection.
cassandra.tcpNoDelay
Disables Nagle's algorithm on the underlying socket. Corresponds to java.net.SocketOptions.TCPNODELAY.
cassandra.consistencyLevel
Sets the default consistency level of the Perform Cassandra Query assertion.
Default:
ONE
