Input 

Document

• Min: 1

• Max: 2

• Mapper

• Copy

Requires the Schema name and Table name to process a certain number of input documents into a prepared insert query and execute all of the prepared input document values on that query as a batch.

Output

Document

• Min: 0

• Max: 1

• Mapper

Snap outputs the number of documents successfully inserted into the target table in the output view document.

Error

Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter when running the pipeline by choosing one of the following options from the When errors occur list under the Views tab:

• Stop Pipeline Execution: Stops the current pipeline execution if the Snap encounters an error.

• Discard Error Data and Continue: Ignores the error, discards that record, and continues with the remaining records.

• Route Error Data to Error View: Routes the error data to an error view without stopping the Snap execution. Learn more about Error handling in Pipelines.

Label*

Default Value: Oracle - Parallel Load
Example: Oracle - Parallel Load

String

Specify the name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your pipeline.

Schema name

Default Value: N/A
Example: Sys

String/Expression

Specify the database schema name.

Table name*

Default Value: N/A
Example: people

String/Expression

Specify the table on which to execute the load operation.

Create table if not present

Default Value: Deselected

Checkbox

Select this checkbox to automatically create the target table if it does not exist.

• If a second input view is configured for the Snap and it contains a document with schema (metadata) from the source table, the Snap creates the new (target) table using the same schema (metadata). However, if the schema comes from a different database, the Snap might fail with the Unable to create table: "<table_name>" error due to data type incompatibility.

• In the absence of a second input view, the Snap creates a table based on the data types of the columns generated from the first row of the input document (first input view).

Maximum thread count*

Default Value: 0
Example: 20

Integer/Expression

Specify the maximum number of threads allowed to perform data insertions simultaneously. If the value is 0, the snap automatically sets the number of threads equal to the number of available processors on the system.

Batch capacity*

Default Value: 1000
Example: 500

Integer/Expression

Specify the maximum number of records allowed in a single batch for an insertion task.

Snap memory usage: To gracefully handle failed record insertions, the Snap must retain some input document data in memory during the Snap execution. To calculate the memory usage follow this formula:
Max thread count * Batch capacity * 2 * typical record size
For example, with a Maximum thread count of 4, a Batch capacity of 10,000, and an average record size of 50 bytes, the input document data in Snap memory may peak at 4 million bytes.

Maximum error count*

Default Value: 50 
Example:10

Integer/Expression

Specify the maximum number of record insertion errors allowed before execution stops on the next error. For example, if you specify a value of 10, the pipeline execution continues until the number of failed records exceeds 10.

Truncate table before load

Default Value: Deselected

Checkbox/Expression

Select this checkbox to truncate the target table before loading data.

Snap Execution

Default Value: 
Example: Validate & Execute

Dropdown list

Select one of the following three modes in which the Snap executes:

• Validate & Execute: Performs limited execution of the Snap and generates a data preview during pipeline validation. Subsequently, performs full execution of the Snap (unlimited records) during pipeline runtime.

• Execute only: Performs full execution of the Snap during pipeline execution without generating preview data.

• Disabled: Disables the Snap and all Snaps that are downstream from it.
