Input 

Document

• Min: 0

• Max: 1

• Mapper

• JSON Generator

A Snap that can contain data that is to be used with the JSON paths defined in the SQL, if any, or to be passed through.

If the input view is defined, then the where clause substitutes incoming values for a specific query.

Output

Document

• Min: 0

• Max: 1

• JSON Formatter

• Mapper

A document with the result set output, if any, and update count as return status from the Redshift SQL. The Snap output all records of a batch (as configured in your account settings) to the error view if the write fails during batch processing.

If an output view is available and an update/insert/merge/delete statement was executed, then the original document that was used to create the statement will be output with the status of the executed statement.

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 when 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.

Label*

Default Value: Redshift - Execute
Example: Redshift - Execute

String

Specify the name for the Snap.

SQL statement*

Default Value: N/A
Example: "SELECT""EMPNO=$EMPNO and ENAME=$EMPNAME"

String/Expression

Specify the SQL statement to execute on the server. 

Query type

Default Value: Auto
Example: Read

Dropdown list/Expression

Select the type of query for your SQL statement (Read or Write).

When Auto is selected, the Snap tries to determine the query type automatically.
If the execution result of the query is not as expected, you can change the query type to Read or Write.

Pass through

Default Value: Selected

Checkbox

Select this checkbox to pass the input document through to the output view under the key 'original'. This property applies only to the Execute Snaps with SELECT statement.

Ignore empty result

Default Value: Deselected

Checkbox

Select this checkbox to ignore empty result; no document will be written to the output view when a SELECT operation does not produce any result.
If you deselect this checkbox and select the Pass through checkbox, the input document will be passed through to the output view.

Number of retries

Default Value: 0
Example: 3

Integer/Expression

Specify the maximum number of retry attempts the Snap must make in case there is a network failure and is unable to read the target file. The request is terminated if the attempts do not result in a response.

• If the Number of retries value is set to 0 (the default value), the retry option is disabled, and the Snap does not initiate a retry. The pipeline will not attempt to retry the operation in case of a failure—any failure encountered during the database operation will immediately result in the pipeline failing without any retry attempts to recover from the errors.

• If the Number of retries value is greater than 0, the Snap initiates a download of the target file into a temporary local file. If any error occurs during the download, the Snap waits for the time specified in the Retry interval and then attempts to download the file again from the beginning. After the download is successful, the Snap streams the data from the temporary file to the downstream pipeline. All temporary local files are deleted when they are no longer needed.

Retry interval (seconds)

Default Value: 1
Example: 10

Specify the time interval between two successive retry requests. A retry happens only when the previous attempt resulted in an exception. 

Auto commit

Default Value: Use account setting
Example: True

Dropdown list

Select one of the following options:

• True: The Snap enables the auto-commit. The value set on this field overrides the Auto commit property set at the account level.

• False: The Snap disables the auto-commit. The value set on this field overrides the Auto commit property set at the account level.

• Use account setting: The Snap uses the Auto commit value set in the Account. When you select this option, you must enable the Auto commit option in the account settings.

Snap Execution

Default Value: Execute only
Example: Validate & Execute

Dropdown list

Select one of the three modes in which the Snap executes. Available options are:

• 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.

type "e" does not exist

This issue occurs due to incompatibilities with the recent upgrade in the Postgres JDBC drivers.

Download the latest 4.1 Amazon Redshift driver here and use this driver in your Redshift Account configuration and retry running the Pipeline.
