      Specifies a Snowflake table for your node to use.

      Returns:
      Specifies a Snowflake table for your node to use.

    • database

      public final String database()

      Specifies a Snowflake database for your node to use.

      Returns:
      Specifies a Snowflake database for your node to use.

    • tempDir

      public final String tempDir()

      Not currently used.

      Returns:
      Not currently used.

    • iamRole

      public final Option iamRole()

      Not currently used.

      Returns:

    • hasAdditionalOptions

      public final boolean hasAdditionalOptions()
      For responses, this returns true if the service returned a value for the AdditionalOptions property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • additionalOptions

      public final Map<String,String> additionalOptions()

      Specifies additional options passed to the Snowflake connector. If options are specified elsewhere in this node, this will take precedence.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasAdditionalOptions() method.

      Returns:
      Specifies additional options passed to the Snowflake connector. If options are specified elsewhere in this node, this will take precedence.

    • sampleQuery

      public final String sampleQuery()

      A SQL string used to retrieve data with the query sourcetype.

      Returns:
      A SQL string used to retrieve data with the query sourcetype.

    • preAction

      public final String preAction()

      A SQL string run before the Snowflake connector performs its standard actions.

      Returns:
      A SQL string run before the Snowflake connector performs its standard actions.

    • postAction

      public final String postAction()

      A SQL string run after the Snowflake connector performs its standard actions.

      Returns:
      A SQL string run after the Snowflake connector performs its standard actions.

    • action

      public final String action()

      Specifies what action to take when writing to a table with preexisting data. Valid values: append, merge, truncate, drop.

      Returns:
      Specifies what action to take when writing to a table with preexisting data. Valid values: append, merge, truncate, drop.

    • upsert

      public final Boolean upsert()

      Used when Action is append. Specifies the resolution behavior when a row already exists. If true, preexisting rows will be updated. If false, those rows will be inserted.

      Returns:
      Used when Action is append. Specifies the resolution behavior when a row already exists. If true, preexisting rows will be updated. If false, those rows will be inserted.

    • mergeAction

      public final String mergeAction()

      Specifies a merge action. Valid values: simple, custom. If simple, merge behavior is defined by MergeWhenMatched and MergeWhenNotMatched. If custom, defined by MergeClause.

      Returns:
      Specifies a merge action. Valid values: simple, custom. If simple, merge behavior is defined by MergeWhenMatched and MergeWhenNotMatched. If custom, defined by MergeClause.

    • mergeWhenMatched

      public final String mergeWhenMatched()

      Specifies how to resolve records that match preexisting data when merging. Valid values: update, delete.

      Returns:
      Specifies how to resolve records that match preexisting data when merging. Valid values: update, delete.

    • mergeWhenNotMatched

      public final String mergeWhenNotMatched()

      Specifies how to process records that do not match preexisting data when merging. Valid values: insert, none.

      Returns:
      Specifies how to process records that do not match preexisting data when merging. Valid values: insert, none.

    • mergeClause

      public final String mergeClause()

      A SQL statement that specifies a custom merge behavior.

      Returns:
      A SQL statement that specifies a custom merge behavior.

    • stagingTable

      public final String stagingTable()

      The name of a staging table used when performing merge or upsert append actions. Data is written to this table, then moved to table by a generated postaction.

      Returns:
      The name of a staging table used when performing merge or upsert append actions. Data is written to this table, then moved to table by a generated postaction.

    • hasSelectedColumns

      public final boolean hasSelectedColumns()
      For responses, this returns true if the service returned a value for the SelectedColumns property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • selectedColumns

      public final List<Option> selectedColumns()

      Specifies the columns combined to identify a record when detecting matches for merges and upserts. A list of structures with value, label and description keys. Each structure describes a column.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasSelectedColumns() method.

      Returns:
      Specifies the columns combined to identify a record when detecting matches for merges and upserts. A list of structures with value, label and description keys. Each structure describes a column.

    • autoPushdown

      public final Boolean autoPushdown()

      Specifies whether automatic query pushdown is enabled. If pushdown is enabled, then when a query is run on Spark, if part of the query can be "pushed down" to the Snowflake server, it is pushed down. This improves performance of some queries.

      Returns:
      Specifies whether automatic query pushdown is enabled. If pushdown is enabled, then when a query is run on Spark, if part of the query can be "pushed down" to the Snowflake server, it is pushed down. This improves performance of some queries.

    • hasTableSchema

      public final boolean hasTableSchema()
      For responses, this returns true if the service returned a value for the TableSchema property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • tableSchema
