In the list below, the names of required properties appear in bold. Any other properties (not in bold) are considered optional. The table also indicates any default values, whether a property supports the NiFi Expression Language, and whether a property is considered "sensitive", meaning that its value will be encrypted. Before entering a value in a sensitive property, ensure that the nifi.properties file has an entry for the property nifi.sensitive.props.key.
| Name | Default Value | Allowable Values | Description |
|---|---|---|---|
| Cassandra Contact Points | Contact points are addresses of Cassandra nodes. The list of contact points should be comma-separated and in hostname:port format. Example node1:port,node2:port,.... The default client port for Cassandra is 9042, but the port(s) must be explicitly specified. Supports Expression Language: true (will be evaluated using variable registry only) | ||
| Client Auth | REQUIRED |
| Client authentication policy when connecting to secure (TLS/SSL) cluster. Possible values are REQUIRED, WANT, NONE. This property is only used when an SSL Context has been defined and enabled. |
| Consistency Level | ONE |
| The strategy for how many replicas must respond before results are returned. |
| Compression Type | NONE |
| Enable compression at transport-level requests and responses |
| Keyspace | The Cassandra Keyspace to connect to. If no keyspace is specified, the query will need to include the keyspace name before any table reference, in case of 'query' native processors or if the processor supports the 'Table' property, the keyspace name has to be provided with the table name in the form of <KEYSPACE>.<TABLE> Supports Expression Language: true (will be evaluated using variable registry only) | ||
| Username | Username to access the Cassandra cluster Supports Expression Language: true (will be evaluated using variable registry only) | ||
| Password | Password to access the Cassandra cluster Sensitive Property: true Supports Expression Language: true (will be evaluated using variable registry only) | ||
| SSL Context Service | Controller Service API: SSLContextService Implementations: StandardSSLContextService StandardRestrictedSSLContextService | The SSL Context Service used to provide client certificate information for TLS/SSL connections. | |
| Read Timout (ms) | Read timeout (in milliseconds). 0 means no timeout. If no value is set, the underlying default will be used. Supports Expression Language: true (will be evaluated using variable registry only) | ||
| Connect Timout (ms) | Connection timeout (in milliseconds). 0 means no timeout. If no value is set, the underlying default will be used. Supports Expression Language: true (will be evaluated using variable registry only) |
