CassandraSource Class

  • Reference

A copy activity source for a Cassandra database.

All required parameters must be populated in order to send to server.

Constructor

CassandraSource(*, additional_properties: Dict[str, MutableMapping[str, Any]] | None = None, source_retry_count: MutableMapping[str, Any] | None = None, source_retry_wait: MutableMapping[str, Any] | None = None, max_concurrent_connections: MutableMapping[str, Any] | None = None, disable_metrics_collection: MutableMapping[str, Any] | None = None, query_timeout: MutableMapping[str, Any] | None = None, additional_columns: MutableMapping[str, Any] | None = None, query: MutableMapping[str, Any] | None = None, consistency_level: str | _models.CassandraSourceReadConsistencyLevels | None = None, **kwargs: Any)

Keyword-Only Parameters

Name Description
additional_properties
dict[str, <xref:JSON>]

Unmatched properties from the message are deserialized to this collection.

Default value: None
source_retry_count
<xref:JSON>

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

Default value: None
source_retry_wait
<xref:JSON>

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

Default value: None
max_concurrent_connections
<xref:JSON>

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

Default value: None
disable_metrics_collection
<xref:JSON>

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

Default value: None
query_timeout
<xref:JSON>

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

Default value: None
additional_columns
<xref:JSON>

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

Default value: None
query
<xref:JSON>

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

Default value: None
consistency_level
str or CassandraSourceReadConsistencyLevels

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. Known values are: "ALL", "EACH_QUORUM", "QUORUM", "LOCAL_QUORUM", "ONE", "TWO", "THREE", "LOCAL_ONE", "SERIAL", and "LOCAL_SERIAL".

Default value: None
