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: 8192 (hostDistance=LOCAL); 256 (hostDistance=REMOTE)From version 9.4 CR1, the default value is 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 (Available as of Version 9.4 CR1) | Sets the default consistency level of the Perform Cassandra Query assertion. Default: ONE |
