Document

If the input view is defined, the WHERE clause can substitute incoming values for a given expression (to use the Snap as a lookup).

• Mapper

This Snap has one output view by default and produces one document for each row in the table. A second view can be added to output the metadata for the table as a document.

• Mapper
• JSON Formatter
• File Writer
• Redshift - Insert

Label

String

Required.

Required. Specify a unique name for the Snap. Modify this to be more appropriate, especially if more than one of the same Snaps is in the pipeline.

Redshift - Select Default value:

Example: Redshift - Select

Schema name

String/Expression/ Suggestion

The database schema name. Selecting a schema filters the Table name list to show only those tables within the selected schema. The property is suggestible and will retrieve available database schemas during suggest values.

[None] Default value:

Example: public

Table name

String/Expression/ Suggestion

Required.

Name of table to execute select on.

Example: people

Where clause

String/Expression/ Suggestion

Where clause of select statement. This supports document value substitution (such as $person.firstname will be substituted with the value found in the incoming document at the path). However, you may not use a value substitution after "IS" or "is" word. Please see the examples below:

[None] Default value:

Example:

• email = '[email protected]' or email = $email
• email IS NOT NULL
• email IS NULL

Order by: Column names

String/Expression

Enter in the columns in the order in which you want to order by. The default database sort order will be used.

Example:

• name
• email

Limit offset

Integer/Expression

Starting row for the query.

Default value: [None]

Example: 0

Limit rows

Integer/Expression

Number of rows to return from the query.

Default value: [None]

Example: 10

Output fields

String/Expression

Enter or select output field names for SQL SELECT statement. To select all fields, leave it at default.

Default value: [None]

Example: email, address, first, last, etc.

Fetch Output Fields In Schema

Checkbox

Select this check box to include only the selected fields or columns in the Output Schema (second output view). If you do not provide any Output fields, all the columns are visible in the output. If you provide output fields, we recommend you to select Fetch Output Fields In Schema check box.

Default value: Not selected

Pass through

Checkbox

If checked, the input document will be passed through to the output view under the key 'original'.

Default value: Selected

Ignore empty result

Checkbox

If selected, no document will be written to the output view when a SELECT operation does not produce any result. If this property is not selected and the Pass through property is selected, the input document will be passed through to the output view.

Default value: Not selected

Auto commit

Dropdown list

Select one of the options for this property to override the state of the Auto commit property on the account. The Auto commit at the Snap-level has three values: True, False, and Use account setting. The expected functionality for these modes are:

• True - The Snap will execute with auto-commit enabled regardless of the value set for Auto commit in the Account used by the Snap.
• False - The Snap will execute with auto-commit disabled regardless of the value set for Auto commit in the Account used by the Snap.
• Use account setting - The Snap will execute with Auto commit property value inherited by the Account used by the Snap.

Default value: False

Number of retries

Integer

Specifies the maximum number of attempts to be made to receive a response. The request is terminated if the attempts do not result in a response.

If the value is larger than 0, the Snap first downloads 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 attempts to download the file again from the beginning. When 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.

Ensure that the local drive has sufficient free disk space to store the temporary local file.

Default value: 0

Example: 3

Retry interval (seconds)

Integer

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

Default value: 1

Example: 10

Match data types

Checkbox

Conditional. This property applies only when the Output fields property is provided with any field value(s).

If this property is selected, the Snap tries to match the output data types same as when the Output fields property is empty (SELECT * FROM ...). The output preview would be in the same format as the one when SELECT * FROM is implied and all the contents of the table are displayed.

Default value: Not selected

Staging mode

Dropdown list

Required. when the value in the Number of retries field is greater than 0.

Specify the location from the following options to store input documents between retries:

• In memory: The query results are stored in the Snaplex memory. If the query is too large to fit in the memory space, it may cause the Snap to fail, choose the On disk option.
• On disk: The query results are stored on the disk in a temporary (tmp) directory that is managed by the SnapLogic platform. This directory is deleted automatically when the Snap terminates.

Snap execution

Dropdown list

Select an option to specify how the Snap must be executed. Available options are:

• Validate & Execute: Performs limited execution of the Snap (up to 50 records) during Pipeline validation; performs full execution of the Snap (unlimited records) during Pipeline execution.
• Execute only: Performs full execution of the Snap during Pipeline execution; does not execute the Snap during Pipeline validation.
• Disabled: Disables the Snap and, by extension, its downstream Snaps.

Default value: Validate & Execute

Example: Execute only
