CassandraSource()

Initializes a new instance of CassandraSource.

Properties

AdditionalColumns

Specifies the additional columns to be added to source data. Type: array of objects(AdditionalColumns) (or Expression with resultType array of objects).

To assign an object to this property use FromObjectAsJson<T>(T, JsonSerializerOptions).

To assign an already formatted json string to this property use FromString(String).

Examples:

  • BinaryData.FromObjectAsJson("foo"): Creates a payload of "foo".
  • BinaryData.FromString("\"foo\""): Creates a payload of "foo".
  • BinaryData.FromObjectAsJson(new { key = "value" }): Creates a payload of { "key": "value" }.
  • BinaryData.FromString("{\"key\": \"value\"}"): Creates a payload of { "key": "value" }.

AdditionalProperties

Additional Properties

To assign an object to the value of this property use FromObjectAsJson<T>(T, JsonSerializerOptions).

To assign an already formatted json string to this property use FromString(String).

Examples:

  • BinaryData.FromObjectAsJson("foo"): Creates a payload of "foo".
  • BinaryData.FromString("\"foo\""): Creates a payload of "foo".
  • BinaryData.FromObjectAsJson(new { key = "value" }): Creates a payload of { "key": "value" }.
  • BinaryData.FromString("{\"key\": \"value\"}"): Creates a payload of { "key": "value" }.

ConsistencyLevel

The consistency level specifies how many Cassandra servers must respond to a read request before returning data to the client application. Cassandra checks the specified number of Cassandra servers for data to satisfy the read request. Must be one of cassandraSourceReadConsistencyLevels. The default value is 'ONE'. It is case-insensitive.

DisableMetricsCollection

If true, disable data store metrics collection. Default is false. Type: boolean (or Expression with resultType boolean).

(Inherited from CopyActivitySource)
MaxConcurrentConnections

The maximum concurrent connection count for the source data store. Type: integer (or Expression with resultType integer).

(Inherited from CopyActivitySource)
Query

Database query. Should be a SQL-92 query expression or Cassandra Query Language (CQL) command. Type: string (or Expression with resultType string).

QueryTimeout

Query timeout. Type: string (or Expression with resultType string), pattern: ((\d+).)?(\d\d):(60|([0-5][0-9])):(60|([0-5][0-9])).

(Inherited from TabularSource)
SourceRetryCount

Source retry count. Type: integer (or Expression with resultType integer).

(Inherited from CopyActivitySource)
SourceRetryWait

Source retry wait. Type: string (or Expression with resultType string), pattern: ((\d+).)?(\d\d):(60|([0-5][0-9])):(60|([0-5][0-9])).
