PostgreSQL - Bulk Load
PostgreSQL - Bulk Load
May 07, 2024
On this page
Overview
Use this Snap to bulk load data into PostgreSQL tables. If the target table does not exist in PostgreSQL, you also have the provision to create the table.
This Snap supports both binary and document inputs. You can configure the input view in the Views tab.
Additionally, this Snap supports a maximum of two input streams which is useful in sending table schema to the Snap if the target table does not exist. You can mix and match binary and document input views based on the input type.
If the target table does not exist and the input is binary, the Snap does not fetch the table's schema from the input. The table's schema must be passed to the Snap through the second input view. Known Issue: If database metadata from an upstream Snap contains geography column data such as modifiers, those modifiers may not be written to the target table. Workaround: To write geographic data to the target table, create the table using the PostgreSQL - Execute Snap.
Troubleshooting
None.

Mapper Snap

PostgreSQL Select
The data to be loaded into the PostgreSQL table. This Snap has one document input view by default.
A second view can be added for metadata for the table as a binary or document stream so that the target absent table can be created in the database with a similar schema as the source table. This schema is usually from the output of a database Select Snap.
If the schema is from a different database, there is no guarantee that all the data types will be properly handled.

Min: 0
Max: 1
JSON Formatter + File writer
The Snap outputs one document specifying the status, with the records count that are being inserted into the table. Any error occurring during the process is routed to the error view.

Description
Label*
N/A
Specify the name for the account. We recommend that you update the account name, if there is more than one account in your project.
Default Value: N/A Example: Load Employee Data
Schema name
N/A
Specify the database schema name in PostgreSQL. In case it is not defined, then the suggestion for the Table name retrieves all table names of all schemas. The property is suggestible and will retrieve available database schemas during suggest values.
Default Value: N/A Example: Employee
Table name*
N/A
Specify the PostgreSQL table on which to execute the bulk load operation.
If database metadata from an upstream Snap contains geography column data such as modifiers, those modifiers may not be written to the target table. For example, if the column metadata contains a polygon modifier, that modifier will not be written to the target table. Workaround: Create the table using the PostgreSQL - ExecuteSnap.
Default value: Not selected
Columns
N/A
Specify the columns to be loaded/copied. If you do not configure this field set, then all columns in the input data stream are loaded into the target table. You can also set how the null values should be handled for each column.
Column order is critical when using the binary input view.
Force Non-Null and Force Null can both be selected simultaneously. In such cases, the Snap converts quoted null strings to null values and unquoted null strings to empty strings.
Default Value: N/A Example: Load Employee Data
Column
N/A
Specify the name of the column/field. This is a suggestible field and lists all field names in the input.
Default Value: N/A Example: emp_name
Force Non-Null
N/A
Select this check box to not match the selected column's value against the null string. The Snap reads empty null strings as zero-length strings rather than nulls, even when they are not quoted.
Default Value: Not selected Example: N/A
Force Null
N/A
Select this check box to match the selected column value against the null string, even if it has been quoted. If a match is found, the field value is set to NULL.
By default, where the null string is empty, the Snap converts a quoted empty string into NULL.
Default Value: Not selected Example: N/A
Format
N/A
Choose the data format to be written. This field is applicable only when using the binary input view.
Text - tab-separated-values (default)
CSV - comma-separated-values
Binary - PostgreSQL specific format
Default Value: Text Example: CSV
Header Provided
N/A
Select this check box to include the input data has a header. Applicable only when using binary input view and CSV option in the Format field.
Default Value: Not selected Example: N/A

Snap Execution
N/A
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.
Default Value: Execute only Example: Validate & Execute
